I had the exact same experience with the G/Y as Al. They work great than all of a sudden they would be done. I tried the M/T's for a season. They seemed to work well except at the local track. Track prep varied from really bad to poor. A buddy was using Hoosiers and he was able to hook much better then I could. So I put a set of those on and they seem to work pretty well. Time for another set so I'm debating which flavor this time. BTW, I run a 33x16 with a soft compound.
