I started doing DEs back in 1993. "Street" tires were pretty much crap back then. About the best I ever personally used were either the Yokohama AVS Intermediates or A008s. Most everything else just could not hold up under hard track use. So...most of us transitioned to R-compound tires.

Fast forward to 2014 and I start racing in the ChampCar endurance racing series. They require tires with a treadwear rating no lower than 180...so street tires. I was skeptical at first, but my experience is that the current crop of street tires are awesome. They are sticky, predictable and last a long time on the track.

We are currently running Hankook RS-4s and turned 1:45-1:46s a month ago at Road Atlanta in what is basically a mechanically stock E36 (1992 BMW 325is). The FTOD during that race was ~1:37. On street tires. And, we ran 14 hours on the same set of tires. And plan to run the same set of tires at NCM next week. Crazy.
