well i'll tell you from experiance that a rear blow out sucks and is nothing to sneeze at i was doing about 60 fixing to hit an interstate interchange and it almost got real ugly really quick ,and i was in a car ,now i imagine it would be worse in a truck with a larger tire and i have about 15 years of driveing experiance behind the wheel with a lot of dirt road powerslides during the learning years ,not much scares me but that blow out sure did
