I too have had issues with the OEM tires on my 2012 Montana. Last was two weeks ago on a trip to Sevierville, TN from Indiana. TPMS alarm went off, but not until after the tire had blown and damaged the rear sheet metal over the tires. Goodyear Marathon tires 235/80 R16 tires. This is the third original tire that has gone the same route. Pressure and temperature were in the normal range prior to failure. Didn't hit anything. I think that Keystone put too light a tire on these units. Had a buddy with a 2010 Montana, very similar circumstances. I've upgraded now to 235/85 R16's. We'll see how those work. Higher speed rating and heavier load rating although I don't load my camper heavy, don't carry much water, and don't normally run more than 62 or 63 mph. My personal opinion is it's a Keystone issue and not necessarily a Goodyear issue.
It's both a Keystone issue =and= a GY issue. GY for making junk that's wildly overrated and Keystone for putting this junk on their products. No different from any other RV mfr... An E rated Marathon should not be used on anything > 8K GVW, IMO, and should =still= be changed after 3 years.
