Bridgestone Potenza RE-71R UHP Summer 205/55R16 91V Passenger Tire

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

I drive track days up and down the East Coast. Because I drive to these events, I need good track capability and a DOT rating so that I am legal travelling to events. I have been running the RE-71R for about 1 1/2 years now and am into my fifth set. The tire is addictive. While the tire has excellent grip (the best of any streetable tire I have tried - and I have tried several), it's overall controllability is its most important feature to me because, in the long run, you are not at a track day to win anything. Turn in is crisp and definite. It has a wide range of controllability such that you can make corrections anywhere and catch the tire if you overcook it. Braking control is equally impressive. The tire does require attention by the driver, however. It does not like excessive heat and you have to keep a close watch on tire pressures, reducing pressure as the heat builds during the day. If you don't, the tire will lose some grip and wear quickly. Road performance is adequate, but you don't buy this tire for its road performance. It gets you to the track - which is its normal habitat!
