RIGHT FRONT TIRE 245/45R19B 102.H.M.S I HAD A MAJOR BLOWOUT. THE SIDEWALL OF THE TIRE HAD A WHOLE THE SIZE OF A RETANGULAR BRICK. i COULD HAVE LOST CONTROL AND HURT MYSELF AND OTHERS. I HAD MY BRAKES REPLACED AND THE TIRES ALIGNED AND BALANCED A COUPLE OF DAYS BEFORE. THE MECHANIC SAID IT WAS UNUSUAL FOR THE TIRES TO SHOW WEAR ON THE OUTSIDE AND INSIDE TREAD. AT 75 MPH IT WAS LIKE A LOAD EXPLOSION. BECAUSE THEY ARE RUN FLAT TIRES I DID NOT BRAKE AND COASTED TO THE EXIT WHICH WAS CLOSE BY. INSURANCE CLAIM WAS FILED AND ADJUSTER REVIEWED THE TIRE, THEY DID PAY FOR A NEW TIRE AND LABOR, I HAD TO PAY FOR REALIGNMENT THE CAR WAS FLAT BEDDED TO THE NEAREST MERCEDES REPAIR SHOP. THE TIRE WAS REPLACED AND THEY REALIGNED AGAIN. THEY SAID I WAS VERY LUCKY NOT TO HAVE HAD A MAJOR ACCIDENT OR EVEN DONE MORE DAMAGE TO THE CAR. THE MECHANIC SAID TO CHECK FOR RECALLS BECAUSE THE OF THE RECTANGULAR SIZE ON THE SIDEWALL OF THE TIRE. I DID NOT RUN OVER ANYTHING IN THE ROAD. THE CAR ROAD SMOOTHLY AFTER THE TIRE WAS REPLACED I HAVE THE SAME TIRE ON THE RIGHT FRONT. I AM VERY NERVOUS IT COULD HAPPEN AGAIN.
