Eric,

Thanks for your reply. I have had 2 sets of Conti Contact Touring on my Crossfire. It was abit strange that my first set (OEM on the car) had so much longer tread wear than the second set. I called Conti (here in Canada) and spoke with customer service. They had me take my car to an authorized dealer for inspection, who found no mechanical issues with the car that would account for the abnormial wear and tear. After 2 calls back to customer service, it turns out that they tires have a 60,000 mile tread guarantee. The prorated my tread use and I'm getting a 47% discount on the tires. The dealer has to order the tires in and I expect to have them installed next week.

Phil ...
