I put a set of PR2 tires on in the spring and have about 2500 miles on them .The front has a line just off center which looks like a seperation of the dual compound , it is not straight but very ragged also the tire has an odd wear pattern . Took it back to the dealer purchased at and they were no help at all just normal was the comment . I do not want problems with the front tire ,does anyone have any suggestions .
