Filthy new Pirellis

So, Tire Rack shipped my new Pirelli P-Zeros to a local shop where I had them mounted, balanced, etc.

Tire Rack page for P-Zero-Nero

I saw them right when they arrived at the shop, and they were incredibly filthy on delivery. Some slightly sticky grey-brown coating all over the sidewalls. I figured it was just dirt, or tire bloom, and I'd be able to wash it off. WRONG. Here's a photo of one of the tires after nearly two hours of scrubbing with soap and a scrub brush.

I'm very leery of putting any kind of dressing on the sidewalls until, somehow, I get this crap off of them. But meanwhile it runs entirely counter to my personal automotive ethos to drive around with tires looking like this
And the Pirellis do need breaking in.

Poetic Justice Dept: One reason I replaced the OEM Michelins a bit early is that I didn't think they looked good enough.

And, of course, the TPMS still isn't working. The dealer has "fixed" that three times now.

Constructive advice welcome...

If greased lightning doesn't take care of the problem, you're more or less screwed.

RE: Filthy new Pirellis

Naw, to minimize suspense here I'll provide an exciting update. Turns out this gummy crap can be rubbed off even though it cannot be brushed or wiped off. My tire guy showed me this morning how you can do it with your thumb, with enough pressure; presumably an eraser would work as well. (He said he's infuriated when tires arrive in this condition, because the customer always complains. Go figure.

You have to be very careful what chemicals you permit to come in contact with your tires btw.  It remains unclear whether this substance is 'tire bloom' or residue from the releasing agent sprayed into molds to permit the tires to be freed during manufacture.

Of course, this cleaning will now be an extremely laborious process, not least because the 'darkened' areas of the sidewall are actually composed of miniscule radial striations which means that rubbing across them will be useless. Speaking of useless, I really have nothing better to do with my time than spend another few hours trying to clean these brand-new tires. What luck

Do a burnout. The tire dust will then collect on the goo if it's still sticky and form a layering of black tire over it. Problem solved.

LOL...Genius!  ...of course, it's hard to do burnouts without exceeding 2000 rpm

Just spray a little bit of tyre dressing on a small part and see how it goes, tyre cleaner in a can my even take it off.

RE: Filthy new Pirellis

Here's a photo of the striations.  Miniscule ribbing.  Not sure it makes sense for keeping clean.

Gee, looks kinda gnarly up close for a brand-new tire huh.

So how'd you end up cleaning them?

RE: Filthy new Pirellis

Unbelievably tedious.  Here's the plastic eraser with a half-cleaned tire!  It is useless on the striations, incidentally.  But easier on the skin than using one's thumb.  And did I mention that I have tendinitis at present

Also, I did one tire with NZB's method and it looks good.  The real test will be if it still looks good after weather, etc.  Because I presume the goop is still there, underneath the tire dressing.

RE: Filthy new Pirellis

Ahem, yes I know this is bordering on lunacy

Anyway, to improve the tone of the thread, here's the one done NZB style

Next, once the tires are broken in, I'll report on how well they perform

You think the goo will wear off over time?

Re: Filthy new Pirellis

Ah, NZB style the lazy man's way....

Come to think of it an orbital buffer may have been the best way kinda too late now though, if you'd thought lazy like me you would have got it.

RE: Filthy new Pirellis

Who knows, orbital buffer might have worked, but I doubt it would get in between the striations (miniature ridges) ... they're the ones really breaking my back on this.  No Animals I don't think the goop would wear off, I think it would just attract more dirt.  My hope on the NZB wheel (just one so far) is that the tire dressing is undergoing a chemical reaction with the goop and merging into a permanent, black coating.  It's a theory

Would it be uncouth for me to suggest you worry about something less trivial?

Go drive the darn thing and stop obsessing over how it looks.

Don't forget to clean those calipers while you're at it.

Dirt isn't all bad, you know.

I'm still cleaning dirt from places I never knew could get dirty on the neon-- A friend had a party, and another friend got his ghettosled(cutlass rwd) stuck in wet grass... The entire driver's side was covered in 1/2 inch of mud.

Re: Filthy new Pirellis

How are the tyres to drive with and did the cleaning work?
