As you can see from the above discussion, there is no end to opinions on which tire is best. TireRack has an excellent website where you can compare tires on several different aspects. I suggest you go there to educate yourself on tire characteristics. Be sure you know and understand the tire size and weight rating the RV manufacturer recommends. BTW, in my experience Tirerack is a good place to buy from. I have compared their prices to local dealers and WalMart and they equal or beat them even considering the price you have to pay to have someone mount the tires. I have no connection with Tirerack other than my experience buying several different sets of tires from them. The last tires I bought for my RV were Michelin LTX MS2. There were a couple of other tires that met my specifications, but I ended up going with the Michelins because of a $70 rebate they were offering at the time.
