Auto-X/Street Tire Choice.

[Loren]

Any of those would be fine for street use and mediocre for autocross use.

For serious grip, the current best street/autox tires are (in order from good to better):
Hankook RS2
Falken Azenis
BFG Potenza RE-01 (on closeout, possibly cheap)
Dunlop Direzza Z1 Star Spec
Toyo R1-R

Most of those can be had for under $100 in 15" sizes (except the Toyos), don't know about 16s. Check the status of the closeout on the RE-01 at the Tire Rack, the prices were GREAT, and it's a fantastic tire!

I autocrossed both the RS2 and the RT615 while the RT615 had better turn in feel, I did better with the RS2, it may have been due to running in colder weather, it seemed to me like the RT615 needed to be really hot to work, on cold days in the spring and early fall the RT 615 fell short.
