WE WERE DRIVING HOME ON HIGHWAY 81 FROM YANKTON, SD INTO NEBRASKA. WE NOTICED DEBRIS FLYING OFF THE TIRE & THEN THE HUB CAP FLEW OFF OF OUR 2006 COACHMEN VELOCITY TRAVEL TRAILER. WE STOPPED IMMEDIATELY & NOTICED THERE WERE FLAMES BETWEEN THE 2 TIRES ON THE PASSENGER SIDE. WITHIN MINUTES, THE ENTIRE CAMPER WAS ENGULFED IN FLAMES. LUCKILY SOME PEOPLE ASSISTED IN UNHOOKING THE PROPANE TANKS AND TRUCK FROM THE CAMPER. IF NOT FOR THAT, OR IF WE HAD NOT NOTICED THE FLYING DEBRIS, THIS COULD HAVE TURNED OUT TO BE EVEN WORSE OF A TRAGEDY. IT SEEMS ODD THAT A BLOWN TIRE WOULD CAUSE THIS TO HAPPEN. *TT
