SIENNA 2004 AWD, PULLING TO THE RIGHT, UNRELIABLE RUN-FLAT TIRES- NEEDS REPLACEMENT ALMOST EVERY 12,000 MILES. I JUST HAD IT REPLACE LAST YEAR 2006 AS SPONSORED BY TOYOTA BECAUSE THEY SAID ORIGINAL TIRES WERE DEFECTIVE. NOW I AM HAVING PROBLEMS, GRINDING NOISE WHILE TURNING RIGHT, AND WAS INFORMED THAT ALL THE TIRES NEED TO BE REPLACED AFTER AT APPROXIMATELY 12,000 MILES , ODOMETER SHOWED APPROX 25,000 MILES, BECAUSE OF UNEVEN WEAR MOSTLY LEFT FRONT OUTSIDE PART OF THE TIRE. DEALER SAID BECAUSE I HAVE BEEN RUNNING ON LOW PRESSURE AND WAS PROBABLY MAKING A LOT OF RIGHT TURNS. IF I MAKE A RIGHT TURN I WOULD MAKE AN EQUAL AMOUNT OF LEFT TURNS. THE VAN WAS EQUIPPED WITH LOW PRESURE MONITORING SENSOR, ONE OF THE REASONS I PURCHASED IT WHICH DID NOT GO OFF. *AK TOYOTA REFUSES TO HELP WITH ALL THE TIRE PROBLEM AND DEALER IS PLAYING DUMB TO THE ISSUE.
