As much as it stinks to lay out the cash for a new (to you) camper, and then have to spring for tires at the same time, that is the best advice you can get if you have GY Marathons or any other E rated ST tire. Well, maybe not Maxxis, but anything Keystone puts on there is likely gonna disappoint you. Heed the call. Do not roll the dice with your tires (pun intended). If you need proof, do a search on tires here and you'll have plenty of information. I bought my Montana used at a dealer and they put new Marathons on. Everybody here said to ditch them, but I thought I was smart enough to get by. All I had to do was watch my weights, pressures, speed and all would be good. I didn't have any catastrophic mishaps like some here, but I barely made it through my first season. Those tires had less than 2000 miles on them. A bubble in the sidewall of one convinced me not to go any further with them.
