FR sent our trailer with spare rim rated for 2150 lbs. with D range tires rated for 2450 lbs. I believe and I'm looking at E range Maxxis.
"At this point in time, what difference does it make?"
What it boils down to is your perception of safety. I'm surprised your would contemplate using tires with a maximum 80 PSI rating on rims with 65 psi rating.
Why did you not return the spare tire/rim assembly to FR?
Tire manufacturers must provide a list of acceptable rims to be used on every tire they make. They must provide access of such lists to the public. All tire retailers have such listings for the tires they carry/sell.
Vehicle manufacturers are required to make tire/rim fitments that are appropriate, meaning the OE fitments meet minimum standards for the vehicle they are fitted to.
When making selections for replacement tires other than those the size of the OE tires, an owner really needs to consult with tire retailers that are fully trained in the procedures that follow tire industry standards for such fitments.
If you are so dissatisfied with the OE tires that came on your unit why would you use your replacements on rims that are not earmarked for the tires you want to use?
