The contact owns a 2000 Nissan Frontier equipped with firestone primewell tires, size: 215/65/r15. While driving approximately 65 mph, the contact felt a vibration in the tires. The contact discovered that the sidewall was separated from the thread of the rear passenger side tire. The vehicle was taken to an independent mechanic where the technician stated that the tire needed to be replaced. The tire was replaced. The manufacturer was not notified of the failure. The approximate vehicle failure mileage was 107,183 and the tire failure mileage was 319.

Brand new tires with less than 500 miles on them, after 2 attempts they still would not take a balance. Owner determined by spinning the tires on the vehicle that the tread block wobbled side to side and the sidewall height varied as the tire was rotated. Vendor replaced two of the four tires under warranty.

While cleaning truck, I noticed hundreds of small cracks in the tire sidewall area on all four tires. All small cracks were on the sidewall that was exposed. No cracks were observed on the inner sidewall area. No failure noted as of now but I'm leary about keeping these tires on the vehicle for safety reasons. The tires are michelin xcx/apt truck/SUV tires that were installed on 10/2004 and they have only 33,268 miles on them so far (60k mile warranty). The vehicle is a 2000 Nissan Frontier xe, v6, 2wd. The tire size is p235/75r15.
