We had a '01 Dodge 2500 we drove 50,000 miles with no tire problems at all. rotated them at 5000 miles and checked pressure regularly. This truck has 9600 miles on it and rotated the tires at 6500. If you blow a rear tire at speed, put the "pedal to the metal" until you have it under control, then gently slow it down. If the tire's blown, you'll not hurt it any more.
