I've had the C7 six months. When I picked it up the tires had some kind of tire dressing on it. I haven't used any. Now the tires have a brown film that is tough to get off. Reg car wash soap didn't do it and it took 6 scrubbings with comet to get it off of one tire. What is it and what gets it off easier?

Try other strong cleaners like Simple Green, 409, etc. on a Scotch Guard or Brillo pad. Maybe you'll hit on something that will break it up. Solvent (e.g., naphtha, Coleman lantern fluid) or alcohol might work, but those chemicals might be hard on the rubber. In any case I would follow up with a good cleaning with Dawn and then once thoroughly cleaned treat with rubber conditioner (303, ArmorAll, Vinylex, etc.).

Black magic bleach white.....boils it right off the tire.

Any idea where/when the coating was applied? It doesn't seem like something that would be done at the factory or at BG.

I'm
Thinking it's residue from the dealer's tire dressing.

Simple green is working but still slow going.

Thanks I'll get some

Dawn dish soap. Should strip off the film.

Search/ Google TIRE BLOOM on the web or autogeek.net....happens a lot on new cars....EZ fix....

Wow! Lots of good reading. I don't notice it as bad on my other cars, but they get driven in all kinds of weather and don't get washed as often. Since the Vette is mostly dusty I don't scrub the tires as much.

Keep them clean, and they look good.

The brown film is partly from the tire dressing dealers put on the tires and part of the asphalt from highways.

You can take it off by using wally worlds Purple cleaner, for best results put it on warm (not hot) dry tires in the shade.

Spray it on let it sit a few minutes then spray it again then wash the tire with any car soap using a wheel brush the stiffer brush the better it will scrub.

I have a soft brush for wheels and a stiff plastic bristle for tires.

For best results clean the tire a few times once you have it black or as near to black as tires get today don't put anything on the tires again.

Tires are not as black as they used to be because they use less carbon black in the rubber. I have been told that carbon black is expensive and they don't use as much to tint the rubber black

When I bought my C7 I asked the dealer clean up guy not to put anything on the tires they still look good 4K miles later.

I also use the Griots cleaner, it leaves a nice natural finish on the tires if you prefer not to use any dressing.

Available from Autogeek will do a great job removing the browning, silicone-based tire dressings, dirt, and grime from your vehicle’s tires.


If wanted, follow with a coat or two of:

The more coats you apply the glossier look you will get (one coat has almost no gloss). This stuff lasts for months, will not turn brown and actually protects your tires by preventing leaching of antiozonants and UV absorbers.

My guess and thinking it is brake dust. The tire reacts differently with it and it becomes brownish. All my cars that have open wheels turn the tires brownish. I have started to use wheel cleaner on the tire as well with a light scrub and its gone. The if I want apply a tire shine.

Your theories on why they turn brown are interesting because when I took delivery of my 16 last week they were brownish and I didn't let the dealer clean or detail the car.

It is in the tire makeup not the brake dust, google it, as I said above.Of course if you just wanna keep guessing, be my guest:

Hee hee, gotta' chuckle at some theories.

WelderGuy

If it's really anti-ozonant and it offers some protection for the tires, wouldn't it be better to leave it be?
