Tire Swap
Looking at changing my 235/80 16E tires for a set of 245/75 16E Michelin Ribs on my 5th wheel. For those that have done it, anything I should be concerned about with the very slight difference in size...

Over pressuring a tire.
Using pressures above max on the Marathons is old old news and gets neaten to death on RV forums. Not a good idea IMO on a ST tire that is a marginal tire to begin with. I would ask your ST tire dealer if he will give you any warranty help on a tire that has been pumped to 10 psi above max sidewall pressures on a heavy trailer.
I've seen my 16" load E tires go to 92-93 psi in the hot summer when running the interstate at max loads on my equipment trailers. If the E tire was 90 psi cold set now it could be 100 PSI

Trailers unlike a car/truck are very forgiving when it comes to handling issues. One big reason is the axle/axles are close set in the center of the trailer unlike a truck with axles at the corners. All the trailer has to do is follow the tow vehicle.
Sure....at some point a wheel can be too wide or too narrow but not the 245/75 on a 6" trailer wheel.
Now a LT245/75 on a truck with 6" wide wheels is a completely different animal and can create steering/handling issues.
