You have to try Mitchelin XGT Z4s first! Threadwear rating is a wopping 300!!!! These puppies last forever! Handling is just superb (what else would you expect from the company who INVENTED Radials) I have a set on my 97 GTP (www.gtpforsale.com) and the tires have over 36,000 miles on them, yet there is still a good 10,000 worth of tread left, and these are Z rated tires!!!! 46,000 miles WOW!
