2011 Alpine 3450 wheels

Does anyone know the PSI rating on the rims on this RV Thanks

Since the trailer comes from the factory with load range E tires and since trailer manufacturers rarely give more than needed I would say the rims are rated for 80 psi. JM2¢, Hank

I would check the back side of the rims. Ours are embossed on the back side of one of the spokes. Just an FYI, ours did come with the Marathon "E" rated tires, but the rims are rated to 110 PSI and now sport the G614 "G" rated tires.

Thanks that is what I want to do change out my tires

I am curious as well, my new alpine 3600RS has E tires now. When I change them in 4 years I would like to go better on load rating as well.

I had the same question on my Alpine rims and I contacted Keystone to see if the rims were rated at 80 or 110 psi. They could not answer the question so they gave me the number to their vendor. I contacted the vendor and they told me to look on the backside of the rim for a stamp. If 3250 was stamped on the rim it was a 80 psi "E" rated rim. If 3750 was stamped on the rim it is 110 psi "G" rated rim.

what are G rated tires?

Max Load 3,750 pounds @ 110(PSI) Single *This tire requires a special high load capacity wheel and high pressure tire valve.

Lots more if you just Google search on "lrg tires" without the quotes.
