1986 DODGE RAM Tires Problems

I WAS DRIVING HOME FROM VISITING FRIENDS WHO LIVE ABOUT 13 MILES FROM ME ON A HOT SUN. AFTERNOON ON A 2-LANE COUNTRY ROAD. I BEGAN TO NOTICE SOME SWAY ON THE CURVES ABOUT 1/3 OF THE WAY HOME. AS I WAS DRIVING INTO THE CITY LIMITS I REALIZED THE REAR TIRE HAD GONE FLAT BUT DROVE ABOUT 1 BLOCK SO I COULD PULL OFF SAFELY. AS A RESULT THE TIRE RECEIVED SOME DAMAGE WHICH MADE IT DIFFICULT TO DETERMINE THE EXACT CAUSE OF THE FLAT. I HAD IT REPLACED AT THE SAME FIRESTONE DEALER I BOUGHT IT FROM BUT WAS PUZZLED BECAUSE IT SEEMED TO BE VERY CHEWED UP FOR THE SHORT DISTANCE I CONTINUED TO DRIVE ONCE I NOTICED THE FLAT. THE TIRE WAS ONE OF FOUR I BOUGHT TOGETHER LESS THAN A YEAR AGO BUT THE ONE WHICH WENT FLAT WAS REPLACED BEFORE WORD OF THE PROBLEMS...

FRONT RIGHT SHOULDER/LAP BELT LATCH BROKE UPON IMPACT; RIGHT REAR TIRE BLEW; VEHICLE HIT DIRT BANK; TUMBLED OVER.; VEHICLE TOTALED. TT
