Not sure what axle weight Thor put on the unit, it's gross weight is 9000 something. Our stuff has probably added another thousand fifteen hundred.
Think you may be confused about gross weight....The unit should have a placard on it some where showing the units GVW..that is how much the unit can weigh...loaded....You state it's 9,000#, then say you've added another 1500#:h..So I'm figuring the "empty" or "dry weight" is 9,000# and you've added an additional 1500#, making it weighing around 10,500#...GVW is probably, or should be higher...
"IF" the unit came with E rated tires as you've indicated, odds are your 5er has no heavier than 6,000# rated axles....IF so, the Michelin XPS RIB would be a much better route to go than the Michelin LT that you're talking about....IF too pricy, the Duravis R250 is as good a tire and not as expensive.
I would't "crimp" on tires, no matter how often you tow...it only takes one blowout to ruin your trip and possibly cause enough damage to the 5er that it could be out of commission for a bit. If you can't afford the RIBS, go with the Duravis R250 tire....
