Question:
My Forrest River Classic Signature Super Lite came from the factory with st225/75r15 “D” rated tires. I would like to know if it is safe for my rims to handle the same size tires except in “E” rated tires. How would I be able to find out if my factory rims can handle the increase in rating with the jump from 65psi on the D rated tires to 80psi on the E rated tires? This doesn’t seem to me like it should be a problem since I am not planning to carry any more weight than I did with the D rated tires. Will the increased max pressure of the E rated tires create any problems that would require me to upgrade to heavier duty rims?

Expert Reply:
The rim itself would have no problem handling 80 psi as most trailer wheels easily handle quite a bit more. The valve stems might need to be upgraded to a higher capacity but normally that's replaced at the time of a tire replacement anyway. For a Load Range E tire in the size ST225/75R15 we have the Karrier part # AM10303 which has a capacity of 2,830 lbs at 80 psi and a speed rating of 81 mph.
