Carrier/rack problems of the 2002 BMW 3 Series

Michelin pilot sport a/s plus tires 275/30/19 on BMW m3 had blow out on freeway at normal speeds of 65 mph. Could hear rubber whipping the road just prior to the abruptly bursting. Had tires inspected and technician found excessive cracking near the tread and center wear-bar had pitting in the rubber (15,622 miles). Car is seldom driven and always garaged (climate controlled). Tire store had seen identical issues in the past with same tire. Did not want to replace with same tires that potentially have the same issue. Lost warranty credits to purchase another brand for family safety. These tires are not safe and need to be reviewed for material and engineering design. Particular vehicle does not hold a spare. Endangerment from potential injury and being stranded in an isolated area.
