Gauging interests on (4) RE070 tires off '05 sti taken off at 3000 miles. Never raced on, but one tire had a nail puncture. I fixed it and drove a few hundred miles with it with no problems. I'm no tire expert but treadlife I'd say is more than 95% left.I'd like $350 for all four.
The puncture was right on the edge of the tire. Don't know if it's still safe anymore but I had no problems when I rode on it.
