Can I use LT truck tire on my 5th wheel?

Does anyone see any issues with this, as long as there's no clearance problems with the inch greater diameter?

The truck wants to run at 72 MPH in the right RPM range, and dropping to 65 kills me on every little hill...

A 245/75/16 might be a little closer fit to your 235/80s

That might work, as long as the load range is right. Thanks!

Edit: just looked on Tire Rack, and the 245's load range, while still "E," drops by 400#. The 265 is the only size close to the ST tire's load rating...

Ahh, gotcha. I don't think the 265 will be that big of a size issue on most campers.
Good luck!!
