10 ply tires?

I have a Forest River 5th wheel. The cousin to the Rockwood. It has the Aluminum rims and they are stamped "Maximum load 2830 pounds", the same as what's stamped on my new tires, but no mention of maximum pressure they can handle. I recently did just what you are wanting to do. I got rid of the **** D rated China tires and bought E rated Goodyear Endurance tires and I'm now rated to 87 mph and max cold inflation is 80 psi. I've seen 90 psi when traveling when the tires are hot. I don't have a lot of miles on them (about 400 miles so far) and I've had no issue at all.

No issues that I can see as long as rims can handle the additional psi, did the same thing many moons ago, really nice to have more safety margin.

Crawl under the trailer with a flash light and a rag. Look at the back side of your rims for a max inflation stamp.

Unless it's stamped in the valley, which means that a tire would have to be dismounted to check.

NO issue IMHO, as you should be running nearly the same air pressure as with the "D" tires.

I highly recommend GY ENDURANCE.

No problem with higher load range tires......but why do you think you need extra pressure ??

That number on the sidewall is NOT a recommendation for any particular application.
