If tires only last 2 to 4 years with low miles, there has to be other serious issues that should be addressed.

Key to that statement is properly loaded. That is the whole problem with LT tires on rv"s is that the tires are overloaded and overheated all the time. Its not like on a pickup truck that you go to the home improvement store twice a year and put a bunch of weight in and drive 5 miles to your house. This is like loading your pickup with stone and driving across the country, several times. LT tires on a pickup have to carry 5-7000 lbs. On an RV they are carrying 15,000 lbs. Big difference. All class A's and super C's come with commercial tires for that reason. Its actually a shame that they still equip class C's with LT tires in the first place.

It's not something you even consider when you are purchasing though, who is really thinking about tires when buying one. Not until you get it home, park it in the garage and see that your tires are squatting before you even put anything of your own in it.
