DUNLOP GRANTREK TIRES Complaints

Putting air in my tires I noticed cracking on all tires on the outside of the sidewall area and not just in one location. It appears all around in a line on each tire.

The contact stated while driving 70 MPH, the vehicle started shaking abnormally. The contact stated no warning light was illuminated. The contact was able to continue driving to her destination. The contact took the vehicle to the local dealer to be diagnosed. The contact was informed that three of 4 tires needed to be replaced. The dealer replaced the four tires. The manufacturer had been informed of the failure. The failure mileage was 31,386.

TIRES ARE NEW 3500 MILES. NORMAL DRIVING AT 40 MPH LOUD NOISE COMING FROM TIRE AND BLEW OUT. THE STEEL BELT WAS FAULTY. TWO DAYS LATER LOUD NOISE COMING FROM ANOTHER NEW TIRE TIRE OUT OF ROUND DUE TO STEEL BELT FAILURE. NO ROAD HAZARD SO TIRE DEALER SAID EVEN THOUGH THEY ARE NEW IT WILL BE ANOTHER 880.00.
