So assuming my tanks are dry, all cabinets and fridge are empty, once I add my 300# carcass and a few cans of beanie weenies, I'm over the max. (which irks the HECK out of me).



I've been told this limitation is because of the LT225/75R16 Load Range E tires it came from the factory with. Although they're difficult to find online, I hear there's a load range F available. Assuming I replace all six, would this allow me to carry more beanie weenies or maybe even a 12-pack of PBR?



Would this be a wise move? The tires only have 3000 miles on them, and I'm going to be loading up to go full time by October and plan to travel quite a bit. Should I upgrade the tires, or just buy the Good Sam Platinum plan so the expected blowouts will be replaced for free?


Many thanks for your wisdom!

No. The GCWR and GVWR are based on the mechanical limitations of the chassis and not the load rating of the tires.
