I have a used set of 195/50R15 Bridgestone Potenza RE-01R's that I ran on my civic all last season for AutoX. I put about 25 AutoX events on them and 1 Novice school. I only drove on them to, during and from events. Tread depth new is 9/32's, 2 tires are at 5/32's with the edges at 4/32's and the other 2 are at 6/32's with the edges at 5/32's. These tires still have a lot of life left in them, easily for another full season. They are very good tires, I took the Street Touring Class Championship on them last year with Washington D.C. Region and Autocrossers Inc, as well as the Small Bore Series with Capital Driving Club. They have been sitting in my garage since the beginning of this season when I replaced them. No longer need them. I am Located in Howard County, MD. I will NOT ship these, pick-up only. If interested please e-mail me at rubberduckieracing@yahoo.com. I paid about $450 for the set brand new early last year, will set these at $200OBO.
