Does anyone have any autocross experience with the Goodyear Eagle F1 Supercar 3R tires with the treadware of 100 particularily on a C6 2013 Grand Sport? I'm curious if they're any good. I would like to run my car in some low-key events like NCCC events and I don't want to get crazy with various sizes tires that will create havoc with the ABS and traction control systems and the Goodyear tires are the only brand of tires that with match the 275-35-18 & 325-30-19 combination. I prefer to run the Michelin Sport Cup 2 tires but, they don't have a 275-35-18 tire to match up with the 325-30-19 rear tires. They do have the 285 and 295s but they are the 30 aspect ratios and smaller than the 275-35 tire thus may not play well with the 325 rear tire.

I looked into possibly using a reproduction Grand Sport 19X10 wheel and run a 285 or 295 which will play with the 325 rear tire but, the off-set is way off. So, either I run the Goodyear 3Rs or invest in a set of Forgelines and get the off-set I need to run a 19X10 wheel in front in order to run the Sport Cup 2 tires.

I am only running the Grand Sport occasionally so I really don't want to invest in a set of Forgelines just for an occasional low-key event.

Thanks for your response. I think I'll stick with the Goodyear's.

You are going to have a tough time getting 3r's to temp without a codriver and wasting sessions to get them warm... They need lots of heat to perform their best

I can see that be the case if the ambient temps are below 70 or 80 degrees but, what when the ambient temps are above like 90-100 degrees, I wouldn't think heating the tires would be an issue. I would only be running events with my Grand Sport when the ambient temps will be above 85-90 degrees.

Nice thing about R888R and NT01 is that they have a lot of grip at low temps.
