I BOUGHT A NEW 2002 YUKON XL WHICH CAME WITH FIRESTONE WILDERNESS LE TIRES INCLUDING THE SPARE. I HAVE ROTATED ALL TIRES PROPERLY AND ACCORDING TO THE MAINTENANCE SCHEDULE, EVERY THREE TO FIVE THOUSAND MILES. I HAVE HAD THE FRONT END ALIGNMENT CHECK OUT, WHICH WAS FOUND TO BE PERFECTLY IN ALIGNMENT. THE TIRES HAVE 24,000 MILES ON THEM. ALL FOUR OF MY TIRES ARE DEFECTIVE WITH HIGH/LOW SPOTS ON THE OUTSIDE AND INSIDE TREAD. THE THREE CENTER ROWS OF TREAD ARE WEARING PERFECTLY CORRECT AND EVEN. THE TIRE SHOP AND THE DEALERSHIP RECCOMMENDS REPLACING ALL THE TIRES BECAUSE THEY ARE A SAFETY HAZARD AND COULD POSSIBLY CAUSE ME TO HAVE AN ACCIDENT AT HIGHER HIGHWAY SPEEDS.*AK
