I'm looking for new tires 235/40/17 for a '93 325is. Budget is always a consideration it seems. :) Looking for a good overall street tire/occasional track use, don't NEED total MAX performance, but will take the car to the track once or twice a year (beginner). How do the two compare? What's the wear rating on the Kumho? Any comparison with the Toyo Proxes T1-S? Thanks!
