Never thought about it like that. What is the difference between a autocross compound vs road course compound ? c51 vs c71, a6 vs r6? I was under the assumtion autocross compound took to heat quicker ? If so, Im lost

Autox compounds don't require heat or as much of it to work. Makes them good for Time Trials and such where you don't get 2-3 laps to heat them up.



So I've had the Rivals on for a day or two and I'm kinda on the fence about them. They are certainly good tires and have quite excellent grip, but I can't seem to get them to breakaway like I want, I'm not sure if that's a good or bad thing.

I've also been unable to induce massive tire squeal that most others have so I may not be pushing them hard enough yet, but I have seen 1.18g on them right out of the box during a test run whiich is pretty amazing.
