I was washing my 2001 CVT today and noticed all 4 of my tires have sidewall cracks in them. This really has me upset. The car only has a tad over 13k miles. I looked over the Bridgestone Limited Warranty booklet and it doesn't look like they are cover under the warranty anymore. I don't understand it, I have another car, a 1996 with its original tires and they aren't cracked. But my 3 year old Insight's tures are. Has anyone else had this issue?
