We have ran Phoenix tires since the late 90s,we just received a new set a month ago and I think something has changed at Coker. We have not hooked the new tires up, out of 15 passes we have hooked once. I called Coker tire and they sent me another set and we are spinning these also real bad. My car has gone from a giant wheelstander to a tire spinning pig. Hoosiers are in our future.
