MY 2010 G37 INFINITI IS EQUIPPED WITH MICHELIN PILOT SPORT A/S 3 TIRES, SIZE 245/45R18. ONLY HAD THE VEHICLE 30 DAYS AND WHILE DRIVING APPROXIMATELY 55 MPH ON HIGHWAY, THE REAR PASSENGER SIDE TIRE BLEW OUT AND CAUSED THE VEHICLE TO CRASH. THE VEHICLE WAS DAMAGED BAD AND NOT DRIVABLE AND HAD TO BE TOWED. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED BECAUSE IT DID NOT INVOLVE ANOTHER VEHICLE. THE TIRE WAS A REPLACEMENT TIRE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE VEHICLE FAILURE MILEAGE WAS 52,000 AND THE TIRE FAILURE MILEAGE WAS UNKNOWN. NOT SURE OF THE DAMAGE COST DONE TO VEHICLE.
