I have a full set of BFGoodrich gForce R1 225/45ZR17 that i got off a set of wheels i recently bought. i have never run these tires but the member who did use them said "They are take off from Playboy MX5 cup car. Shaved, qualifying session, race session. I mounted them but never got around to using them." about 45 mins to an hour of use. check out the pics 350$b/o + shipping if that's what you want. if you want more pics let me know.

location is NJ 08816
