Here is the part I have trouble understanding. When RV owners switch from ST Tires to LT tires do they also suddenly no longer underinflate or overload them? If most ST tire failures are due to under inflation and overloading why do those same RV owners have so much better luck with LT tires? Are these same RV owners inoculated with something when LT tires are installed? The ST defenders argument's don't hold water IMHO.
That is the one test that LT tires have done and ST tires dont on their way to getting the DOT stamp. Underinflation at speed.
The construction of the two are different. The ST sidewalls are built stiffer and because of that they heat up faster and farther than LT's when underinflated. They pretty much have to be run at max psi because of their makeup. The LT's are fairly forgiving in that regard as they have to meet the testing for that.
One other point (just for reference) is to go from ST to LT you generally have to go up in size on the LT to regain the carrying capacity that the ST had. Thats because of the sidewall construction isnt as stiff on the LT. So once you get the right LT size you are good to go with a cooler running tire.
