4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | 463 with larger tires - ESP problems solved Darren at Collie Autoworks is not only one heck of a knowledgeable G mechanic (ask him anything about 463 electronic troubles, and he usually knows a remedy without even looking it up) he let me play with the input options for larger tires to solve my ESP interferences due to the 295/75R16 tires that I had mounted on my G500 some time ago. The calculated difference between stock 265/60R18 (2367 mm) tires and the new 295/75R16 (2590 mm) tires is about 10%. Enough to freak out ESP in fast turns - especially downhill. We went into the transmission setup (not into the instrument cluster as recomended by some). The optional 8.25R16 with U=2620 mm tire size is closest to the 295/75R16 (2590 mm). But we did not put the 8.25R16 in, since we also discovered that you can modify the setting for the diffs. Would it be possible to combine the diff setting with the tire settings? We chose 235/85R16 (2475 mm) - a 4.5% gain plus 4.111:1 diffs - an additional 6% gain all in all 10.5% - 10% was needed very cool! Speed indicated and miles driven on the instrument cluster is still off. So the instrument cluster setting should also be adjusted (next time when I am in San Rafael). First results: the G500 is noticeably more responsive, accelerates faster and shifts differently, fuel economy improved by 10% (calculated with GPS since instrument cluster is still off). And the best thing is that ESP is no longer acting up. Now that's a major improvement. Amazing what a willing mechanic can do for you. Now, based on the fact that you can combine diff and tire settings, you could input 4.111 gears and 8.25R16 tires - that would allow you to run 35" tires without upsetting ESP. http://www.collieautoworks.com Edited by 4x4abc 11/7/2007 1:00 AM (tires.jpg) (axle.jpg) Attachments ---------------- tires.jpg (68KB - 42 downloads) axle.jpg (51KB - 22 downloads) | ||

KERR Date registered: Dec 1899 Location: Vehicle(s): | Re: 463 with larger tires - ESP problems solved Man i wish he was not in san rafeal!!! i would spend more moeny to get my esp fixed.. With you finding out this information about the trans and the diff computers would it be possiable to now install lower gear like 5:33 or something in the G then have him work his magic. Id kill for lower gears to get my bottom end back. Then look into doing a GV overdrive kit to give me two more gears for free way crusing. His next trick need to be to develop a computer program that will let used down load the info off there G's computer and send it to him for modification then he can e mail it back... With LS1 edit on GM cars and the aem on the supra you can share files. Im sure there is nothing like that for the benz though.. | ||

UN Mobile Date registered: Dec 1899 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved Greetings, I have 235/85/16 tires and have already made the adjustment in the computer for that size and it did change the driving charecteristics some but my ESP problems persist. Would you suggest some other tire/axle ratio?? I will be taking my G500 up to San rafeal for some maintenace in the the near future and will add this to the list that Darren can help me with. | ||

4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | RE: 463 with larger tires - ESP problems solved Todd, was the change made for the instrument cluster or for the transmission module? The instrument cluster settings affect only speed and miles (signal comes from front left wheel) - no effect on ESP The transmission module settings affect shift points, engine management and ESP (signal comes from input shaft plus all 4 wheels). Also, 235/85R16 is only 1" taller than stock - and I am surprised to hear that you had ESP problems at all. You could experiement with the 8.25R16C setting. I am certain, Darren will help you out. I am more than happy with the results. I stepped on it really hard yesterday (driving faster than I normally would) and only got a little flickering of the triangle out of it - not the aggressive brake interference I had to deal with before (I always had one foot lightly on the brake pedal to fool the computer into "thinking", I was in control of the situation). Without activating the brake control switch in tight fast turns downhill, ESP would send me into oncoming traffic or into the ditch (ESP always "steers" you out of the turn) Edited by 4x4abc 11/7/2007 11:21 AM | ||

UN Mobile Date registered: Dec 1899 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved Harald, Both, the transmission module and the command/nav unit were updated. Your description of the ESP pulling violently to the outside of turn is what I have experienced. Hopefully the other size, input into the transmission module will settle it down, otherwise I will be grounding (through a switch) pin 7 on the locker cluster. Which will disable ESP ABS BAS. Off Topic: I will be meeting a small group of guys mon. the 12th at 9:30am to run up Fordyce creek, starting at the staging area off of Eagle lakes exit. I will probally go all the way through to Meadow lake and return to Truckee via Hwy 89. Mostly a jeep and Toyota crowd as Fordyce is fairly severe. You are welcome to join us. | ||

4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | RE: 463 with larger tires - ESP problems solved Todd, so many playgrounds - so little time. I'll be in Death Valley with the G-expedition For on-road travel I would not want to lose ESP, ABS, BAS and Elektronic Brake Force Distribution - they are too valuable to be sacrificed. I would rather have continued to feather my brakes to keep ESP from acting up. But no more need for that sfter the computer correction. | ||

It is great to contemplate but even if the gear sets are out there, they are over $1000 a set. That is before installation. You would have to REALLY want it done. When I had gears done in my 280 by Europa, the bill by then end exceeded $9000.00 and I provided the new CV joints | ||

Wolfgang Date registered: Dec 1899 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved The calculated difference between stock 265/60R18 (2367 mm) tires and the new 295/75R16 (2590 mm) tires is about 10%. Enough to freak out ESP in fast turns - especially downhill. Harald, I wonder why your G has problems in turns with big tires but my ML with 33" BFGs has not. Have you updated the ESP controller as specified in the ESP technical bulletin for the W463? Was about 2004 when it was issued. I suspect that may solve your ESP in downhill turn problem. Requires a new ESP module part number 463 545 23 32 which reduces the G's ESP in turn quirkiness. I can post details in case you cant find it. It's on www.startekinfo.com. | ||

4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | larger tires / ESP conflict finally completely solved after changing the transmission control module (4.11 diff plus 235/85R16) all my previous ESP troubles had disappeared - but the display was still off http://www.pointedthree.com/disc/forums/showthread.php?tid=9622&pos... today we changed the setting for the instrument cluster - largest tire size possible is 235/85R16 (no diffs possible or needed - the instrument cluster gets that info from the transmission module) NOW my display shows exactly the same speed (plus minus 1 mph) as my GPS! So, in order to change the 463 system to accept larger tires, both instrument cluster and transmission module need to be fed new numbers.

4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | RE: larger tires / ESP conflict finally completely solved Brent, shortening of the effective length of the panhard rod (projection of rod) combined with the shortening of the effective length of the drag link due to taller springs is in line with the shortening of the panhard by compression bending (bad driving and increased weight of the 463 vs 460) - both will cause EPS to act up becuase the steering angle sensor gets the wrong values. Did you get an adjustable panhard rod? I am thinking of having an adjustable (similar to adjustments in the drag link) panhard fabricated for my future 463 projects.

I am also very interested to find out since my55 is lower stock by an inch than the 500 where is a 55 in comparison to the 500 in regards to steering arm inclination. My steering rod is 14.5 inches from the ground on the right side(passenger side) of the vehicle and the pitman arm side is half an inch less. Is the 500 flat or higher on the pitman arm side? Epc shows different part numbers on pitman arms too between a 55 and a 500 so I am wondering if there is a difference on their heights on that tie rod end | ||

When I'm offroading I let them down to 20psi which makes it a bit more fun but still the ESP doesn't cut in. Edited by Piggysims 11/21/2007 5:16 AM | ||

bwillie Date registered: Dec 1899 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved The springs are all custom with aluminum spacers up front to level. I am still playing with springs and rates. There is no rubbing at all with the 35's. I have an old drag link that I am going bend to try and make up the angle. There is some bump steer but not bad at all. | ||

Skyline Date registered: Dec 1899 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved 4x4abc - 11/6/2007 6:56 AMBut we did not put the 8.25R16 in, since we also discovered that you can modify the setting for the diffs. Would it be possible to combine the diff setting with the tire settings? We chose 235/85R16 (2475 mm) - a 4.5% gain plus 4.111:1 diffs - an additional 6% gain all in all 10.5% - 10% was needed very cool! the G500 is noticeably more responsive, accelerates faster and shifts differently, fuel economy improved by 10% (calculated with GPS since instrument cluster is still off). And the best thing is that ESP is no longer acting up. Now that's a major improvement. Amazing what a willing mechanic can do for you. Now, based on the fact that you can combine diff and tire settings, you could input 4.111 gears and 8.25R16 tires - that would allow you to run 35" tires without upsetting ESP. http://www.collieautoworks.com May I ask why did you choose the 4.111 diffs? They are the longest from all. Wouldn't it be better to go for a shorter one? The 4,857? That's the setting I'm using. | ||

4x4abc Date registered: Apr 2006 Location: La Paz, Baja California, Mexico Vehicle(s): 02 G500 | RE: 463 with larger tires - ESP problems solved Stitch, yes, you are right - physically it would be best to have lower (numerically higher) gears to compensate for larger tires. However, since we did not install lower diff gears , we needed to find virtual settings for the computer to make sense of the lower wheel revolutions created by the larger tires. Since the computer does not have a setting for 295/75R16 tires, we chose 4.111 gears plus 235/85R16 tires instead. If you would use the 4.857 setting in the computer, the system would expect higher wheel rpm than with stock tires - that combined with larger tires would create unhappy settings for the transmission plus all the electronic helpers (ESP etc) Happy Turkey Day!

Are 8.25R 16 about 32.5 inch diameter? | ||

With my 4.111 there must be no other option( I assume with even higher gears) on my set up. I believe 4.11 is the highest you can go (3.72 gears were also made but i think only for 460/461) I need to be totally clear before I ask my tech to go in there and change stuff and see what happens. Are 8.25R 16 about 32.5 inch diameter? yes~33". | ||

Present: Germany Vehicle(s): 2000 g500 Posts: 1887 | Re: 463 with larger tires - ESP problems solved Regarding ESP for turning stability/control, tire width alone basically shouldn't affect things because the relative rotation rates of the different tires shouldn't change assuming the offsets stay the same... so if you're running less offset rims then you do have a non-reversible change that will affect the actual rates in turns. Less offset will increase the relative rates between tires. However wider tires alone could still have an impact if the affect the body roll, such as a wide tire on a narrow rim will likely roll more than the stock configuration unless the tires have a really stiff sidewall. I wonder if lower gears are put in the g55 to improve the mileage because the engine has the power to afford taller gears. I haven't done all the math, but i'm almost positive i've seen a net longterm gain in Mileage going to my heavier/taller 33's, and i'd guess its from lowering the RPM's because everything else should say it's going to increase my mileage. It would tie in with the fact that the 320's get shorter gears. You get better power/driveability with the shorter gears on the 320, and the incremental increase in mileage is offset by the smaller motor. You put in bigger motors, you can afford to drop gearing and maintain/improve driveability and save a little gas given the motor size. Edited by ewalberg 11/25/2007 10:18 PM | ||

chris505 Date registered: May 2007 Location: San Francisco Vehicle(s): '79 280E/'80 280GE/'00 G500 | Re: 463 with larger tires - ESP problems solved ewalberg, have you fiddled with your speedometer to get accurate mpg figures? I am very curious to what my mileage would be with 33s. I am also curious if our pre-'02 G500s have that 8.25R16 option. ps Just moments ago I was telling my girlfriend while driving back from dinner in the mission that I plan to mount 33" tires on the G500, she opposed the idea thinking it would be an "ugly lifted truck with huge tires", I tried to convince her otherwise but she wasn't hearing it, then 6 blocks from our apartment she pointed to the street corner and said "now THAT is what a G SHOULD look like!" believe it or not she was pointing at your truck off Coal!!! | ||

So, in order to change the 463 system to accept larger tires, both instrument cluster and transmission module need to be fed new numbers. Work done at our local G-guru shop Collie Autoworks in San Rafael hope, you don't mind the plug - we need to support the good guys http://collieautoworks.com/ Harald, just a small correction after I looked in the transmission control module for ever..... The coding you are referring to is done in the transfer case control module and I'm still searching for the tire size change in the instrument cluster thing....

Present: Germany Vehicle(s): 2000 g500 Posts: 1887 | Re: 463 with larger tires - ESP problems solved i never saw this question chris505... sorry about that. No i havne't messed with my speedo, but i have measured my odometet/trip distance against a navi so i have been recording my distance traveled and gallons used, and my long term mileage before hand was 14.2 (after corrections, it wasn't that accurate to start) and now it looks based on my estimations (i haven't gone in crunched all the numbers) to be between 14 and 15mpg... 285/70r17's. Highway mileage seems better, city maybe a little worse. they're basically 33's and no lift. my rims at et35 and 8.5" wide. Just the 265/65r18 bfg a/t ko looks quite a bit nicer in my opinion, but i'm most partial to my setup. Glad she liked it... At the tech session at collier's there was a really nice mix of g500 with different rim and tire options. I've never cared that my speedo doesn't read right on... and it doesn't really affect anything else elecronically as far as i can tell. THough i would be curious to see how it changed my shift points, but i've always been pretty happy with them. A bit lazy to downshift as always, but it stays down once it shifts which i like. (no hunting) PS, my spare is in the upper position to keep it out of harms way. | ||

The calculated difference between stock 265/60R18 (2367 mm) tires and the new 295/75R16 (2590 mm) tires is about 10%. Enough to freak out ESP in fast turns - especially downhill. We went into the transmission setup (not into the instrument cluster as recomended by some). The optional 8.25R16 with U=2620 mm tire size is closest to the 295/75R16 (2590 mm). But we did not put the 8.25R16 in, since we also discovered that you can modify the setting for the diffs. Would it be possible to combine the diff setting with the tire settings? We chose 235/85R16 (2475 mm) - a 4.5% gain plus 4.111:1 diffs - an additional 6% gain all in all 10.5% - 10% was needed very cool! Speed indicated and miles driven on the instrument cluster is still off. So the instrument cluster setting should also be adjusted (next time when I am in San Rafael). First results: the G500 is noticeably more responsive, accelerates faster and shifts differently, fuel economy improved by 10% (calculated with GPS since instrument cluster is still off). And the best thing is that ESP is no longer acting up. Now that's a major improvement. Amazing what a willing mechanic can do for you. Now, based on the fact that you can combine diff and tire settings, you could input 4.111 gears and 8.25R16 tires - that would allow you to run 35" tires without upsetting ESP. http://www.collieautoworks.com It's actually the setup for the Transfer Case ("VG" in the photos = Verteiler Getrieb = Transfer Case), not the Transmission as stated above; and it only works on G's that have an ECU for the Transfer Case. My 2000 G500 with a manual selector lever for the TC does not have a TC ECU; and, therefore, does not have these adjustments. Only the Instrument Cluster tire adjustment is available on these models. Of course, I also don't have ESP; so there's no need to have to fool it. | ||

I am going to do a 3" Lift and would like to mount 35's on it. The ECU needs to be reprogrammed in order for it to function correctly. So what exactley needs to be done? After reading this post, I see that I need a StarDiag computer to modifiy the transmission module and the instrument module. What exact parameters need to be programmed in for 2004 G500 with 33" Tires and 35" Tires? I figure MB has this computer and if I can give them specific instructions on how to use their computer, they should be able to do the mentioned mods. Comments? | ||

arthurchapin Member Date registered: Jan 2011 Location: Washington State, USA Vehicle(s): 2002 G500 Posts: 12 | Math check please :) I am going to take my truck in to have the change made this week and wanted to confirm my math with you guys. My new tire size 325/60R18 = 33.22 (manufacture spec) or 9% over stock In Transfercase Setup (VG) there are the following options 265/60R18 - 265/70R16 - 285/55R18 = 30.5" 255/55R18 - 225/75R16 = 29" 235/85R16 - 265/75R16 = 31.75" 8.25R16 = 32.5" (I could be off) Based on this I should select the 31.75" tire size and then select the 4.11 diffs. which would give me 10.5% up or I could just change the diffs and get 6%. Im guessing it would be better to go with the 1.5% over versus the 3% under? Also what are the options for the instrament cluster and which screen is that on? I want to give the shop good directions? I think what I read was that the cluster picks up the diff setting so I should set it to the same 265/75R16 tires that I will set in the VG screen. Does that all sound right? | ||

My esp settings are stock. I find that when I take a moderately aggressive turn, the esp turns on. Secondly, I see that even if I turn off the ESP on the center console, it turns itself back on after 40mph. Thus, if I wanted to lessen the amount of ESP interaction, can I adjust the diff to 4.11:1 or set my tire size to the largest possible? or both? I assume doing this will reduce the amount of ESP activation which isn't good for wet weather? Since I live in los angeles, wet weather and snow are not real issues. | ||

And offroad, or rally driving, you need to learn how to drive with two feet anyway, so this might as well be your excuse to start learning! Most racing schools will still teach heel - toe method (using just one foot) because its still largely based on having a clutch in most sports and race cars that amatuers use. Ofcourse since the betterment of tiptronic and Ferrari F1 paddle shift tech has entered cars like a WRX, etc, some schools are now starting to teach two foot driving. -mserpe not just a G guy...my other history is (a Porsche track school driving instructor 1997-2003) now a private instructor Raced Porsches 16 years Raced Saab and GTI ice and rally cars....where you really learn how to drive 2wd racing in the snow and ice of Maine, Canada, and NY State | ||

Otiswesty Administrator Date registered: Jun 2007 Location: Portland, Oregon Vehicle(s): 463.241, 461.213 Posts: 3004 | Re: 463 with larger tires - ESP problems solved I believe that Karl and Richard have wired in an ESP kill switch that is not limited like the stock switch at 40 mph. The issue with the '05 G55 is likely the yaw sensors that are sensing the pitch or roll of the car in a fast turn. That is the only time I have ESP issues; also with 33.2" tires and a Star computer reset. I think the reason that Karl was having ESP issues was most likely due to this same fact combined with driving roads like Topanga or Malibu Canyon. | ||

I assume doing this will reduce the amount of ESP activation which isn't good for wet weather? Since I live in los angeles, wet weather and snow are not real issues. What is the tire pressure on your tires? Are they stock? Is your tire pressure set at the max values by the manufacturer? The Esp on my truck does not act up even in turns fast enough to burn rubber on turns as long as I do not get on an over or under steer balance and start sliding very fast. Being on the gas instead of the brakes fast into a turn will keep the esp from doing anything at all on an 05 G55 unless you get very deep into loosing control. With 285-65-18 revo 2s and the trasnfer case module on 235-85-16s with 35 psi I feel my truck out handled the stock set up with the soft four ply tires on any surface. For what you seem to like if there is a tire you can get that has stiffer sidewall than stock keeping your truck stock it might help with better handling and no esp issues... How many miles on your truck? Fresh shocks and all suspension components in top shape makes a world of difference keeping your esp from coming active on a G55. Besides shocks being fresh, the roll bar bushings on a G55 can get where they have play from being used enough and cause more body roll than you want to keep the esp snoozing... Mario Mario | ||

Stock tires(size wise) but stiffer sidewall = better handling,including fresh shocks ....lots of miles on your truck? Stock shocks are half gone at 20k if you want handling! With my set up the spring rate is not just red fronts and brown rears. If you do that with other shocks than stock you will not have better handling and if you do so with the stock shocks you will have a rough ride. I have cilastios on my shocks custom build to add to the spring rate in heavier bumps and keep the comfort of red springs on pavement. Your stock amg shocks have them also but when the extension damping forces start going away if your truck has some miles your ride will get rougher and it will not handle as good as new all other components being good. With my tires I found all electronics working better and faster with the 235-85-16 transfer case module setting and I have experimented with all the settings and my tire size. The stock settings with my tire size never had any issues but it was not as fast as stock tires on ice with the stock settings. Red front springs and white rears is bad balance of spring rate on my G at least so the cilastios make it right. If you go to my tire size and springs you will spend a lot of money on custom shocks,panhard rod mod,cilastios(cheap) and some more stuff..... If you do not of road much and just want good handling with out spending too much money,if I was you I would buy some good rubber stock size,new front shocks from a 2011 g55,and I would keep the rear stock..... take the rear shocks out pull the cilastios out and cut half inch of the flat end and put it all back together. I would do this at the rear only if you do not carry four people and lots of luggage when you try to do your sport driving...... You will find out it will increase your front caster slightly (lower the rear very little) increase comfort and sharpen your handling going into corners. The rear shocks are good for 60k plus if you drive pavement mostly. Harald As always I am expressing personal experiences for anyones benefit that wants to know what happens to my truck when I make changes trying to better things for my use....I am not talking theories....so have another cerveza for me Mario | ||

From another thread on which Mario posted ... No problem - I really don't know exactly what it is either :err: ... Thanks for asking the question ... On the G55 they are already compressed some at normal ride height (stock springs) At the rear they are very stiff and the shocks are set to be the same on extension....when the shocks start loosing their effectiveness by loosing force as they wear out the quality of the ride and handling starts to become very bad. The G55 stock can ride like an one ton pick up with bad shocks with enough miles on the clock. There is no esp issues with my set up and I like the extra articulation that I have with the 90 series Konis since the front end has been transformed in traction due to the extra shock travel and all electronics work great with it all. Today I was watching the esp do its marvel at 70mph on Rucker road heading to the west side of the chiricahuas of AZ, a very wide and smooth dirt road with lots of dips and rises and a few sharp turns. The G run great and if I was on the gas through a turn fast enough to slide i could do so with all four with no esp coming on and if I came in a corner too fast and lift with turning the steering fast to where I want to go the esp would cut in very fast correct the balance and still let me keep a lot of speed. With the stock setting and my size tires in the same drive it would let me start over steering before it would cut in very abruptly.....so on the G55 the esp is fast and forgiving to go fast and even though it does not act up if you go up in tire size it does work better adjusted to the change.... Be aware of low tire pressures at speed ,I believe they do cause the esp to behave bad...so I wonder if some that have problems here with esp might be running very tall sidewalls with very low pressures.

Present: Germany Vehicle(s): 2000 g500 Posts: 1887 | Re: 463 with larger tires - ESP problems solved mario, we call them "elastomers" or maybe "bump stops" here. I'm not sure if it's still common, but used to be common in mountains bikes. I wouldn't recommend using them for primary suspension because they tend to be very temperature sensitive (compared to a steel spring). But for bumps stops (just at the end of travel) i think they'd be a good idea. Or in your case of cutting in half an existing elastomer at the end of the shock where it bolts to the axle or chassis, you'll simply be doubling it's stiffness to make it more sensitive. | ||

Present: Germany Vehicle(s): 2000 g500 Posts: 1887 | RE: 463 with larger tires - ESP problems solved it's been noted on several occasions that i recall that the g55 come with lower axle gearing than g55 to help out in gas mileage since they have extra HP. Same story with the g320 i think have higher gearing so they still drive nicely through gears but you pay for a little more fuel using higher RPM on highway, but that way you keep the power feeling nice. | ||

I'm looking to put a 33.2" tire on my cousins G500. Aren't the listed 8.25 R16c tires the Michelin XZL's they put on Canadian trucks, IFAV's etc? I believe this tire is 34" tall. What would be the outcome of using this larger tire diameter for the input on a 33.2" tire vs using the 31.8" of the 235, 85 16? The tire we are looking to mount is the Goodyear Wrangler Duratrac in 275/70/18. Edited by Adoni 2/15/2012 1:00 PM | ||

Any thoughts? JV JV Should your truck be any different than mine on this? I do have adjustment on the instrument cluster and set it at 235-85-16 for my 285-65-18 size of tires. The correction on the speedo was small as it was not that far of any ways since it showed more than real with stock tires before adjusting and real close to real with 285-65-18s Anyone correct me if this is wrong but if I remember right, the important change in the transfer case module does the trick for ESP and etc and the rest..... and the instrument change just corrects speedo and computer estimate on gas mileage.....I wonder why if any would JVs be different.

However still, on very tight "corkscrews" down hill to right or left (read; weight transfer to front) even at 19mph, the truck gets pissed and throws the ESP Bermuda Triangle. I don't expect the Cluster re-coding will help this, but I'd like to make sure my speedo and mpg and everything are as close to spot-on as possible. | ||

Anyone have any more info in changing tire sizes via secret COMAND path on an '03 G500? | ||

Chose these tires because they don't have large lugs on tred pattern, hence making them oem quiet. No hummmming at all. Love the new look. Edited by devildog 6/4/2012 10:43 PM | ||

What settings should I run in the computer. I saw your post but got a little confused. Any clairification would be great..... With the size tire you installed I feel if you set your transfer case module for 235-85-16 you will have great performance out of your esp and etc. Your tires being 285x60%=171mm sidewall x 2=342mm divided by 25.4(one inch in mm)=13.46 inches ,plus 18 inch rim=31.64 diameter tire. Most 235-85-16s are 31.5 to 32 inch diameter tires so that should be the right choice. Considering your tires are wider and much lower profile than same diameter on 16s ,that will give you the advantage of less flex on sidewall and much more effective esp action possibly even better than stock. The opposite applies when installing larger high profile sidewall or even softer winter tires of original diameter which cause esp problems and even more so when under inflated for of road.

michel bertin Veteran Date registered: Jun 2006 Location: SFO Bay Area, CA Vehicle(s): '02 G500, '14 G550 Posts: 124 | RE: 463 with larger tires - ESP problems solved I recently replaced the 265/75R16 E Bridgestone Revo's on my '02 G with the size above, 285/75R16 E Revo 2's. After a long search, I narrowed the choice down to BFG A/T T/A KO D or E load , Michelin A/T 2 or the Revo 2, all 16 or 17 32nd's tread depth. The offroading I do is mostly sandy surfaces and rocky trails, around 20psi warm tire pressure, and I need very safe and sure road behavior. My first Revo's had performed a lot better than prior BFG A/T both off road and on road, never had an issue in 7 yrs. I decided on the Revo 2 after consistent TireRack recommendations and reading every post I could find on many forums. Currently 2K mi on them, very happy. I followed the instructions in this thread to get the transfer case and cluster adjusted, picked 8.25R16 for transfer case and the largest size available in the cluster, 235/85R16. The result is fantastic!! The transfer case ratio had never been adjusted before. This finally cured untimely ESP behaviors I had on curvy roads. I take this opportunity to say Thank You very much to Dutch, Brent and everyone contributing to make this a great friendly useful forum for G lovers. I also put a word (mostly for SFO Bay area owners) for Park Avenue Motors in Palo Alto which has exclusively maintained my G's for 10+yrs to very high standards, Rafael is the master technician who always works on my cars.

michel bertin Veteran Date registered: Jun 2006 Location: SFO Bay Area, CA Vehicle(s): '02 G500, '14 G550 Posts: 124 | RE: 463 with larger tires - ESP problems solved Agree that no person or organization is perfect and there were rare cases early on that I was not happy with Park Avenue. Also I am very demanding in car maintenance, keeping several Mercedes in as new working condition. Park Avenue has been a Mercedes maintenance shop for 30+ years; their general mgr's Dad was one of the early MBUSA mgrs in California, they have master techs who regularly publish in the Star, and Rafael, the only master tech I work with, is the one they trust to solve tricky issues on the most expensive Mercedes plus he treats any of my cars as his own. They solved on my '02 G early on many of the issues discussed in this forum, with the care that only great Mercedes maintenance techs would bring. Rafael also installed Mike Serpe's front bumper with my prior Warn 9000 which he had also installed (the bumper is fantastic and Mike was wonderfully helpful as usual), the ORC blue springs, various protection plates etc on my G; and of course he adjusted the transfer case for the 33" tires. They even have a Hunter machine for road force balancing on which they did the Revo 2's and my prior Revo's. So I highly recommend them to Mercedes and G owners (ask for advisor Paul and tech Rafael...). For anyone interested, I now have the classic G winch bumper and a black G brush guard for sale, plus Europa running boards for short wheel base G; PM me or better, mjbertin@gmail.com. Michel | ||

The truck came with Nitto 285/65/18 tires on stock G55 wheels. It is VERY scary in wide, medium speed turns, especially when decelerating. I was excited to come across this post, especially as I have a startek DAS setup that I've used on other Mercedes. I successfully logged in and changed the settings on the VG for the larger tires, and while the situation seems to be improved, it is still unacceptable with the outside turn wheel locking on medium speed turns. I read with interest about an updated ESP control box, but have found no further info on this - the PN is available (about $1,100) so I'd like more info on it before going that route. Ultimately, I'm probably going to look for a way to disable the ESP if I can't find a way to tame this beast. Any ideas / hints greatly appreciated! | ||

Otiswesty Administrator Date registered: Jun 2007 Location: Portland, Oregon Vehicle(s): 463.241, 461.213 Posts: 3004 | Re: 463 with larger tires - ESP problems solved Apparently with the 2013, the ESP kicks in like an anchor being thrown out the window. My wife's 2006 E320cdi, the ESP does not turn back on at higher speeds with the ESP off switch. Not sure about the later 463's though. My 2002 could only use the ESP off switch below 40 MPH. It is possible to make aftermarket modification to switch off ESP. Well discussed in the forums here. One of the reasons I switched to a 1999 G500 was my dislike for the ESP. I do miss the ETS though, great for snow driving. My first experience with wheel spin was in the 1999. The 2002 had ETS and the 1985 300GD had its own reasons. | ||

I'm guessing this is only because you lost MPG after the tire size switch and more or less went back to the MPG that you got with factory sized tires? Do you happen to know what the max size we can get under our G without modification to the fenders/anything else and only have to get the computers adjusted? Guessing 33's and maybe "some" 34's? Thank you | ||

I went with Duratrac 275/70 R18 and of course there is no tire setting for that size. I searched the forum and this tread seemed to fit the bill. I believe I now have 33's on there? Which would indicate a transmission setting of 4.857? What tire sized settings do I use for the odometer change, or keep it stock? Is it ok if they only change the transmission setting without the odometer changing?
Thanks in advance. David

thebigblue Date registered: Jan 2012 Location: Vehicle(s): | RE: 463 with larger tires - ESP problems solved I´m on 285/65-18 and did not change anything, the speedometer is around 10% too low from factory, mine now is a few % below correct speed. Since the odometer is not 10% above from factory, I just know that my figures will be 10% to high, so I subtract 10% from fuel consumption etc. But it looks like the 4.857 setting will get things back to "normal" | ||

Anyone have tips on what to tell them the settings should be? Thanks I just got the same tire mounted Monday but in 275/70/R18 with no rubbing on a stock G500 BTW for anyone reading this in the future. The way I've read through this thread is the new tire is 33.2" tall compared to the stock size of 30.5". Since 33.2 is 8.14% taller than the stock size I would have to look for some combo in the system close to that, which would either be 4.111 gears(+6.04%) plus 235/75/R17.5 (+2.87%) = 8.91% of total correction. Or not touching the gears and just selecting the 8.25R16C tire option, but im not exactly sure how to read that type of numeric sizing. From using my google fu it looks like its a around a 33" tire but I dont know for sure as some guys on the defender forums claim its a 34" tire. Balto in your case I would just have your shop choose the 4.111 gears which is a 6.04% increase that matches your 6.16% taller tires pretty well. Edited by kotton 12/2/2015 3:05 PM | ||

Does anyone remember where I need to go in order to change the speedometer settings to a larger tire size? Some threads I dug up in other forums suggest its in the NAV settings on the comand unit, but I'm unsure if that updates the speedometer or just the GPS unit. I'm taking out the comand soon anyway to install a new head unit, so I assume I'll have to set the speedometer another way anyway. | ||

The transmission module section that lists different gear settings was the one that effected the function of electronics I do not know if they connect in function or not but when I changed the tire size only first the speedo worked accurately tested by GPS but that by it self had no effect on the workings of esp, when later we changed the settings on transmission module it all worked fine Mario | ||

No problems with ESP. First impression is that the tires are great...very quiet considering the AT tread design. I will run them until the spring at which time I will remount the stock G55 wheels and tires. | ||

Thank you to all those who contributed to the content. I am posting my experiences here in case it is useful to others. My vehicle is a 2005 G55 with stock suspension (as far as I know) I installed BFG AT KO2 265/70-18 tires on OEM G550 18" wheels. There no rubbing issues in normal driving lock to lock. I have done a few days of mild off roading (Class 4 roads in Vermont) and have not had any contact issues there either. My speedo was off and the truck was not shifting when it should. The most noticeable shifting issue was not downshifting when needed on long steady hills. So, with the help of this thread, I decided to make a few edits to the settings. My axle ratio was set to 4.111 and tire size was set to 265/60R18. When I compared the tire sizes, I needed to increase the tire size by roughly 10%. Unfortunately, in my 2005 G55, there were only a couple tire options. I decided on the following changes. In the VG (Transfer Case) section, under Read Coding and Change if Necessary, I set the tire size to 235/85R16 and the Axle Ratio to 4.375. That works out to be almost exactly 10%. I also set the tire size under Special Equipment in the Instrument Cluster section to the same 235/85R16 in order to fix the speedo. The speedo is now very close. It reads ~1MPH low at 65MPH. The shifting is now much smoother when accelerating and downshifts on the hills where I was manually downshifting in the past is very smooth. Acceleration also feels faster, although that could be mental. Thanks again for all those who have posted in this thread and especially to Harald and Karl for the screen shots and clarifying details that helped me figure this out. Thanks, - Jesse Edited by Jesse 1/3/2018 4:03 PM | ||

Im pretty new to the coding segment but i have just installed xentry, vadeamo and DTC Monaco to my computer whith a openport 2.0 reader. Is this changes available in Xentry or do you have to go through the Vadeamo program? I have a G350cdi 2009 and going to put on some 35x12,5r20 tires and wonder if some one can do the math and help me with the numbers I have to change. I have so fare done some reading about vadeamo and thing I can get lightly started, but if some one have a dummy sheet or have time to get me started I can easy pay for that knowledge. | ||
