St tires vs LT tires

Also, as for the "many" tire failures experienced by most of us... There are many reasons. RV manufactures are famous for putting on the lightest axles/tires/rims that they can get away with. We the RV'ers, are guilty of "overloading" those axles/tires/rims! And, many of us are all guilty of running tires well beyond there expiration date! General consensus among tire manufacturers is seven(7) years,then replace. It's very hard for me to do, when they "look" fine. When I haul mine to the dump in six(6) years, I'm gonna "puke" after dropping $2400.00 on them!! memtb
