Any one use these on your stock rims - 205/50-16?

If so, what is your opinion of them for a street and autocross tire?

 

Great choice for a daily driver. They also work nicely on the track.

 

I'm thinking about those or the Pirelli P-Zeros, which cost about 25% more.

 

T1s and A520 make much better auo-x tire. But the RE 730 has better ride and sound qualities for the street. I used to have A520 and now have RE730 (along with R-compounds for the track). I won't get the A520 again, but I might try the T1s.
