+1 on this. I ran off 2 sets of PS2s and they were a very good all around tire, street or track. They are still pretty expensive though. My street wheels currently run Sumitomos and they are a good street tire at 1/2 the price of PS2s. They do tend to overheat quickly when pushed at the track though. My track wheels are running Nitto NT-01s and with 30 heat cycles in they are marvelous.
