Yeah, new tires need to be cleaned before running. This is what I do:
I clean 'em with denatured alcohol, then give them a spin on the tire truer and scuff sand the gloss off carefully. It's very easy to overheat the tires, and that's not good. Fist time on the car, double treat with traction compound (paragon in my case), and then about 5 minutes of zipping around the track to even them out.
Then they get cleaned again with denatured alcohol and they're ready for more paragon and racing.
Tekin & Sweep, thanks for all that you do for you know who!
