Bridgestone POTENZA RE-71R 275/35R18 95W Tire

I've competed in autocross events regularly for the last fifteen years. I've run many vender's R-comp tires. The 200 treadwear RE-71R seems to nearly match the dry performance of several of the R-comp tires and in my opinion, maintains that outstanding performance through twice the R-comp life on a heavier "pony car". I'm driving a 2015 Mustang GT with performance pack, Koni's, and larger anti-sway bar on 285 x 35 x 19 (Rear) and 265 x 35 x 19 (Front) RE-71R's. I consistently record lateral g-forces in excess of 1.15 g's through 50 - 60, (approximately 0.8 mile) autocross runs on concrete. If you want to be competitive in the SCCA street classes, I recommend these. I'm on my third set. My reported mileage may appear low, but I count autocross runs to evaluate my autocross-purposed tires. These hold up very well.

Hands down the best tire ive used for autoX. Ran on both my C prepared 1982 Rx-7 and H stock 2011 mazda 6 for autx events as well as lapping days. Awesome grip! (at the expense of road noise and life expectancy/wear) Helps me keep up to and even pass some of the big boys
