I'd give serious consideration to a tire pressure monitoring system... I can highly recommend the Truck Systems Technology unit (known by the letters TST). Blowouts usually caused by underinflation, which creates excessive heat build-up. I've had great luck with Bridgestone V-Steel 265's - came as original equipment on my 03C190P. After 7 (?8) years/50k miles, still looked new - replaced due to age, not wear. Replaced with same tire model. Have 55k on that set in past 6 years, still minimal wear. Imagine will get a 3rd set in the next year or 2! ST
