Do tire treatments work?
I’ve been using a treatment on my old crusty R comps to bring them back to life and have always wondered if they really did anything. It always felt like they did but I didn’t know if it was placebo effect or not.
I decided to find out. I put on a lab coat and glasses, dug out the Type A durometer, grabbed a clipboard and went to work finding out.
Here is a freshly minted Hoosier R6…
And here is an old crappy one (the kind I run.)
I repeated the test on about a half dozen new and old tires with very similar results.
Then I treated the old tires and got this:
Once again, tested many tires in many spots and results were roughly the same.
Then I changed the formula and process a little (tire off rim, do inside as well, place in plastic bag)….
Back to new numbers 🙂
After running the tires a couple sessions I checked again after they sat overnight:
So there you have it…pretty much exactly what all the guys on the web and my butt said. Does it make a difference? Yes. Are they good as new again? After a few laps, no. They are better than with nothing but not as good as new. It is messy and takes a little time, and who the heck knows if it makes you quicker. I’m probably going to keep doing it when I have the time.
