Just FYI, tirerack now has RE-71R tires for 997 turbos. Reasonable price + fast at NT01s + decent wear for grip

(I just want demand for these tires to continue in the long run, I plan to get 19 inch wheels and run 265/305 on my GT4. I have RE-71Rs on my WRX and use it for commuting actually. They are just a little louder than RE-11s or PSS, wear a little worse, but grip much better)

 

Wonder how these are vs AD08R's. The AD08R's are very hard to beat for a street tire.

 

Well, tirerack doesn't have a direct comparison, however, luckily tirerack has data comparing the AD08R and the RS-3, as well as the RS-3 and the RE71R, so one can figure it out.

It looks like the RE-71R is faster and lasts longer than the AD08R, however, the AD08R is more comfortable and quieter.
