NHTSA Complaint #10397917 — 2011 BMW 535I US

OVER A PERIOD OF 5 WEEKS AND 2300 MILES I HAVE EXPERIENCED SIDEWALL DEGRADATION (BLISTER) FOUR DIFFERENT TIMES ON THREE TIRES AFTER TRAVERSING BROKEN PAVEMENT/POT HOLES AT SPEEDS BETWEEN 25 AND 60 MPH. SINCE THIS SPECIFIC TIRE IS ONLY SOLD ON 2011 BMW 535 AND 550 ALL-WHEEL DRIVE MODELS WITH OPTIONAL SPORT PACKAGE EQUIPMENT, THERE ARE PROBABLY RELATIVELY FEW PEOPLE WHO OWN THE TIRE. THEREFORE, I REQUEST THAT YOU BE ESPECIALLY VIGILANT IN INVESTIGATING ANY POTENTIAL PROBLEM SINCE YOU WILL UNDOUBTEDLY RECEIVE FEW FAILURE REPORTS. BECAUSE I PERIODICALLY CHECK THE TIRE AIR PRESSURE I DETECTED THE PROBLEM BEFORE IT RESULTED IN CATASTROPHIC TIRE FAILURE. THE PROBLEM HAS BEEN EXACERBATED BECAUSE THE TIRES ARE ON BACK ORDER AND ARE NOT READILY AVAILABLE IN THE UNITED STATES. I HAD TO WAIT OVER TWO WEEKS TO REPLACE THE INITIAL FAILURES AND AM CURRENTLY WAITING TO REPLACE ANOTHER. *TR
