I bought tires for the new season, went to starspecs and have my ZII's for sale. They have maybe 70 autocross runs on them. 2 of them had picked up a nail/screw and have patches in the middle of the tread, no issues with holding air/leaks. (repaired by Discount Tire). Tires have about 50% tread left on them. I did not daily drive them, well, I may have been lazy taking them off the car after an event and waited until the following weekend, but mainly they were for autocrossing and the occasional canyon run.
