What is on my tires?

[The Guy]

I just bought a new to me sports car. The car has Yokohama s drive tires. The first time I cleaned the tires using my tuf shine tire brush and apc, I had black stuff that came off the tires and didn’t come off the brush. I have never cleaned performance summer tires, is this just a result of sticky tires? Or is this just product that the PO used? What do you think?

Looks like some solvent/petroleum based dressing the previous owner used.

I had the same thing happen to me cleaning some RV tires a while back. I couldn't get the stuff off my brand new Speed Master brush. I had to throw the brush away.

RV tires can be a whole different animal. Especially those regroovable tires... I’ll never come near any of those tires with a brush again. What a nightmare + ruined my brushes. Lol.

I've seen it on a few vehicles. I don't even try to get it all off anymore. Take some off and tell them it'll have to wait for Mother Nature to work some majic

I took some pictures but you can’t really see anything. It’s been at least a month since whatever the PO put on and a few weeks since I cleaned the tires. Here’s my plan: clean the tires 2-4 times and test some new apc’s I haven’t tried yet/play around with dilution ratios then apply 2 coats of perl.

What are your thoughts?

Most likely some armor all or black magic applied. I would recommend a degreaser undiluted and go from there.

Try stoners tarminator and see if that cleans up your brush. I have had success doing that.

No. I have P-Zero Corsa's on my fun car and they definitely do not do that. Some TufShine (and brush) cleans mine right up.
I have Opti TireGel, 303 Balm, DG Tire Dressing and GTechniq T1 and NONE of them result in that kind of mess.

I'll defer to others to recommend 'what do I do next'. Maybe some serious stuff like Tarminator, TarX, Citrol etc.

No, if it's what I think it is it's some petroleum based product. Extremely thick and greasy. You can touch the tire two weeks after it's applied and it will make your finger/hand black and greasy. From my experience it takes 2-3 cleaning over abot 4-6 weeks to get that stuff off. I've never tried a degreaser, not really good for the tire, but in this case it might work. I worked in the tire business for years. I used to hate it when customers would bring in cars with that crap on the tires.

IDK but after a certain point I wonder if you are just damaging the rubber with all the different chemicals?

The best tire cleaner I've ever used is the Mckees tire and rubber rejuvenator.
