I run 225/50/16 Victoracers on my 98 SVT. I have about 25 runs on them and they are just starting to get really sticky. I think that the fronts are now worn down to about 4/32s. The rears still have the little rubber fingers on them. They are only worn a little on their edges. If you want to make autocrossing real fun, just get race tires for the front. Then you will get oversteer going into lift throttle corners.
