For as many tire manufacturers that are out there, you will get that many opinions. Michelin, Goodyear, Toyo, Sumitomo, Bridgestone, Double Coin, Hankook....all have their supporters and all have their opponents. I've had bad luck with 2 Goodyear tires, but still have Goodyears on my rig. Yes, you will pay more for certain brands over others. Yes, certain brands will ride and wear differently due to the chemical makeup of the rubber. Some tout that they are RV tires while some call themselves truck tires. As long as they are in the right load range for your rig, and are inflated according to the manufacturer's recommendations according to the weight of the rig, and as long as they are maintained properly....AND, unless you're going to be putting a LOT of miles on them over the highways (most RVers don't).....they are ALL most likely going to give you good service over their lifetime. So, shop around for acceptable pricing and a good shop to mount them....and go have fun camping!!!
