NHTSA Complaint #10289739 — 1991 FORD EXPLORER

UNIROYAL TIRE SIDE WALL CRACKS LT 235 75R15 - NO FAILURE - JUST CRACK. ALL 4 OF MY TIRES HAD A SIDE WALL CRACK THE ENTIRE DIAMETER OF THE TIRE ABOUT 3 INCHES DOWN ON THE SIDE WALL . I NOTICED THE CRACK ON THE INSIDE AS WELL SO IT APPEARS THE TIRES HAD SOME ISSUE. I HAD NEVER APPLIED TIRE FOAM CLEANER(ARMOR ALL TIREFOAM PRIOR ) BUT ONE TIME THIS LAST WEEK I DID APPLY SOME AND FOUND THE CRACK. LOOKING UNDER THE 1991 FORD EXPLORER 4X4 I DID SEE THE SAME ISSUE ON THE INSIDE OF A FRONT TIRE AS WELL...I NEVER APPLIED ANY ARMOR ALL TYPE CLEANER ON THE INSIDE EITHER. UNIROYAL FACTORY PHONE SUPPORT BLAMED ME OF APPLYING TIRE CLEANER WHICH RUINS TIRES AND SO DID THE WALMART TIRE STORE STAFF . I NEVER APPLIED ANYTHING AS THIS IS AN OLDER VEHICLE WHICH AND NO PR OR SHOW APPEAL. WALMART REPLACED ALL 4 TIRES ON 10-25-09 BUT THE TIRE PRESSURE WAS NOT 35 PSI ITS WAS AROUND 43 ACCORDING TO MY GAGE..THE TIRES ARE RATED FOR 50PSI. WALMART CHARGED THE PROBLEM TO MY WARRANTY AND THEN WANTED TO CHARGE AGAIN FOR A NEW WARRANTY. THIS WAS A TIRE FACTORY PROBLEM AS BOTH SIDE OF THE TIRES HAD A CRACK NOT A FIELD ROAD HAZARD ISSUE. KINGMAN AZ HAS TEMP RANGES FROM 110 IN JULY TO 9 DEGREES IN WINTER...THIS MAY BE FACTOR. *TR
