2005 BMW 545I Tires Problems

BOUGHT MY TIRE IN FEBRUARY OF 2015. HAD ISSUE IMMEDIATELY WITH IT DEFLATING ON ITS OWN WITH NO NOTICEABLE LEAKS. TOOK TO TIRE STORE I BOUGHT FROM THEY FOUND NO ISSUES. PUT INFLATE A TIRE IN IT AND SEEMED TO HELP FOR 2 MONTHS. DRIVING DOWN THE ROAD THE OTHER DAY MY TIRE SHREDDED AND THE TREAD ALMOST CAME OFF THE WHEEL. GOT THE SAME TIRE ON OPPOSITE BACK WHEEL, HAVE NO ISSUES AT ALL WITH IT.

I AM THE SECOND OWNER OF A CERTIFIED PRE-OWNED 2005 BMW 545I. I PURCHASED THE CAR IN JAN 2009 FROM BMW OF PLEASANT GROVE IN SALT LAKE CITY UTAH WITH APPROX. 35,000 MILES. WHEN I DROVE THE CAR OUT OF THE DEALERSHIP IT HAD DUNLOP RUN-FLAT TIRES ON IT. BY AUGUST 31ST 2010 THE CAR HAD APPROXIMATELY 58,000 MILES ON IT AND NEEDED REPLACEMENT TIRES. I TOOK IT TO DISCOUNT TIRE IN SAN DIEGO(PACIFIC BEACH LOCATION) AND HAD (4) NEW MICHELIN TIRES INSTALLED. I DROVE HOME AND THE NEXT DAY ON SEPTEMBER 1ST 2010 WHILE DRIVING TO WORK ONE OF THE TIRES WENT FLAT. I RETURNED TO DISCOUNT TIRE THAT EVENING AND THEY RE-INFLATED THE TIRE AND PLACED IT INTO A WATER TANK TO CHECK FOR LEAKS. THAT IS WHEN THE EMPLOYEE TOLD ME THAT I HAD A CRACKED RIM. I CONTACTED THE BMW OF SAN DIEGO DEALERSHIP REGARDING THIS...

THE TIRES WORE OUT IN LESS THAN 1000 MILES ON A NEW CAR. THE COMPANY (BMW) WAS AWARE OF THIS PROBLEM BUT DELIVERED THE CAR WITH THE DEFECTIVE TIRES. *JB
