We have the exact same tire wear issue. The OEM Sailuns were garbage. They were wearing off like an eraser removing pencil on paper. Barely got 5,000 miles out of them. I replaced them with Carlisles and have concluded that with higher rated tires like these Carlisles and running at 105 lb I get the best wear but still have excessive wear after 12,000 miles on the front tire on the driver side which is where all our weight is. This side has the kitchen with the longest slide out as well as the bedroom slide out. I’ve spoken with countless people about this including this forum and have concluded that this is a design/engineering issue. I could get slightly longer wear by rotating the tires regularly but have resigned myself to this being the nature of the Montana beast. Change tires every 12,000 to 15,000 miles. Alignment seems like a red-herring and the dealer says the axles are within “manufacturers spec”. Good luck with yours.
