... 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.
Back in 2001 my brother bought a brand new 2002 G500, his first road trip in the vehicle from San Diego to Palm Springs was on a road full of tight corners, same things were happening to that brand new unaltered truck. He soon learned that the brake pedal was unnecessary and just let the vehicle drive itself down the mountain by only steering, by the time he reached Palm Springs the front rotors were warped.
The experience was scary if you are not
aware of the "feature". I was commanding
Karl's machine. With all the bell, whistle,
and warning from Karl, it did not stick to my
ears until I experienced it and I was only
doing 10mph left turn down a steep hill.
Lesson here is to put in an abs disable switch
and keep a reminder of this feature. It is not
that bad once you master this feature.
All the reasons why I am going back to
the old school machine. I told u to keep
crazy red flyer!

Oh it's fine, it just takes some getting used to. I was more concerned with the 50mph sweepers and ESP kicking in. With my changes via Autologic, ESP isn't kicking in then anymore, only very tight corners/downhill especially.
Anyone have any more info in changing tire sizes via secret COMAND path on an '03 G500? |

Tom Deckowski told me about the tire input service menu change in his 2002 G500
I have made the corrections in my own truck via DAS-Star diagnostics input but have not taken the time to look for the service menu. I hope it is not misinformation. Maybe Tom will chip in here. |

Pulled the trigger today on a set of NITTO DUNE GRAPPLERES 285/60/18. 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.

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.

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.

Opinions differ. They are partly responsible for me deciding to do all of my own mechanical work. Then again, I'm pretty much of a dyed-in-the-wool DIY'er anyway.

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.

I have a 2004 G55 that I've owned for about a year - when I first got it, I swapped out the awful G55 springs and shocks for stock G500 ones. 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! |

How, where and what do you "log into to change the settings"?

You need a STAR diagnostic system to do this. |

I have a STAR diagnostics system, and have tried several several configurations of tire size and axle ratio, but the problem persists. Does anyone have any info on the upgraded / modified ESP controller mentioned in one of the early posts on this topic? |

there are threads on how to totally disable the ESP system. you can separately enable/disable ESP and ETS if memory serves me. You can wire in a hard switch. |

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. |

So what sizes besides 265 60 18 can I put on my '02 G and not have to worry about the ESP and/or trying to find a place to fix it?
Was leaning towards Duratrac's but not 100% yet. |

any tire larger or smaller than 265/60R18 will affect ESP
as long as the replacement tires have about 675 revs per mile or 2367 mm circumference in their spec sheets, they are safe to use
