Re: DE Tire Options/Recommendations for 18"s
Mike_in OH: I bought Firestone Indy 500 245-275/35-R19's to try out because they were cheap. These are fine for novice or if you're just out to have fun for low $$, but I wouldn't recommend them for intermediate-to-advanced drivers trying to improve lap times. The grip is manageable, but not great. During turns they have more slide than you would want for optimal speed, but are fun nonetheless because you drive at the edge of grip more frequently during fast sweepers and you can generally feel where it is. Braking is where they don't really hold up well. I have a lot more brakes than tire grip, even running stock pads. It's difficult to threshold brake with these because they seem to lose traction quickly under heavy braking from 100mph+. I end up in ABS a lot more frequently with these tires.
This year I bought a set of 18" rims and I'm planning to switch to a stickier tire and put RS29 pads on the front. I've been debating whether to try RS4's, NT05's or NT01's in 245-275/40-R18 or do RE-71R's in the stock 235-265/45-R19 size. I'm leaning toward the NT01's, but I'm all over the place on this. I need to make up my mind some time this week to get them before my next track day.
