Blow out on I-10
While traveling on I-10 out of California in our 31ft Class "C" motor home we had a tire blow out. It was the inside rear on the drivers side. We managed to limp off the highway and called roadside assistance. Our motor home calls for a tire size 225/75R16 Load Range E. (this tire was three years old) I run BF Goodrich Commercial TA 's This is what I found out from the service man when I asked him what might have caused the blow out. He asked me what pressure I run. I said that I set my air pressure at 70 psi front and 80 psi rear cold before I start out. He told me that it was much to high. The tire says 80 psi maximum cold, but the tire heats up while running and the pressure builds and blows. He said that the tire pressure exceeded the maximum pressure. He said I should run 75 psi cold, coming across the desert in southern Califonia and Arizona, and re-adjusted all my tires accordingly. He inspected all my other tires, and three hours later we were on our way again. Any Thoughts.......

Try nitrogen,a lot tire dealers are starting to use it, tires stay cooler ,saves wear,and milage--mileage not much,but it counts, it will cost.one dealer here in Fl. gets $10 per

I run 125 in my fronts and when hot they go up to 139. Do you have tire pressure monitors? You might had a slow leak, and when it got low and started overheating caused the tire to blow. My tires are 130lbs cold max.

I tend to agree. It's my understanding that the mfg recommended max pressure is on a COLD tire and takes into account the fact that the pressure will increase when hot. I don't know how in the world he can suggest that you lower the pressure you carry without weighing your rig...

Max of 110 PSI in the 5'er and max of 80 PSI in the truck but I run 75 PSI to get good wear and no problems. My 5'er tires are J rated to carry 19,000 Lbs. and the 5'er weighs 15,000 Lbs.
Weigh your rig and then put on tires to carry 125% of that weight. Heavy duty tires give great performance and service.

Can't see that much difference between air and Nitrogen. I have a bottle of liquid Nit here in the garage that we use for purging Refrigeration lines while soldering. Its nice when you can pump them up over 120lbs with the Nit. 600lb regulator.

Air is about 80% nitrogen. And it's free. Save your money, benefits of pure nitrogen in tires are minimal at best.
