OWN A 2006 MATRIX AND HAD ALL 4 TIRES WARE OUT ON INSIDE OF THREAD WITH 21000 MILES ON CAR. DID NOT NOTICE THE PROBLEM TILL CAR WENT OFF ROAD HITTING A TREE. REPAIR SHOP SAID TIRES WERE WORN EXCESSIVELY, AND CAR SHOULDN'T BE DRIVEN. UPON REPAIR, CAR WAS TAKEN TO HAVE FRONT END ALIGNED AND WAS TOLD IT WAS WITHIN TOYOTAS SPECKS, BUT COULD BE CORRECTED TO A TIGHTER STANDARD. CONTACTED TOYOTA AND THEY SAID IT WAS THE TIRES FAULT, WHEN CONTACTED THE TIRE MANUFACTURE(CONTINENTAL) , THEY STATED IT WAS CLEARLY OUT OF ALIGNMENT, AND THEREFORE CAR CAME FROM THE FACTORY LIKE THAT. *TR
