However, on the street I'm not sure you'd gain anything over an RE-71R or any of the other high end EHP street tires unless you're *really* pushing on the roads you drive. I would also think that these, like most r-comps, will heat cycle out and harden up rather quickly with street use and therefore would lose a lot of grip over their life. In any case I have been wanting to try a set out but the only street miles they would ever see would be to and from the track until the very end of their life.
