Looking for the group to educate me about tire/rim ratings and to tell me if my current set up is safe.

My trailer rims are marked with the following data: Max Load 1900#’s, Do Not Exceed 60psi, and DOT T. My tires are ST225/75R15 Load Range D with max 65 psi marked on the tire. My trailer has a published GVWR of 10,000#’s.
Are the rims/tires adequate for my trailer or are either the tires or rims underrated for the trailer? My thinking, which could be flawed, is that the aluminum rims are underrated for the trailer and tires (1900#'s x 4 rims = 7600#s). If I had a tongue weight of 15%, that would leave 8500# of trailer weight on the tires. Loading the trailer to its rated capacity of 10000#'s appears to me would risk the safe operation of the trailer which could lead to possible rim and/or tire failure. Any air pressure in the tires above 60 psi also runs the risk of rim/tire failure.

Are the rims/tires adequate for my trailer or are either the tires or rims underrated for the trailer? Would the group educate me? Am I missing something here?

Good question. I wish I had an answer for you. Is there a tire store, RV dealer, or the like you trust? Maybe run it by them.

On the surface it looks as you have done the 'proper' math and "to me," the setup does look a tad lite.

Keep us posted on whatcha come up with.

I too would call a trailer/RV dealer.

I am no expert by any means, but my 3000# ATV trailer tires, are rated at 1650 lbs at 90 psi. (Single axle trailer (2 wheels)).

I would say No the wheels. Evena complete loaded even distribution of 10,000 exceeds the wheels by a ocuple thousand pounds.

D rated trailer tires should be rated at about 2500 lbs a piece. (2540 # for goodyear Marathon tires).

Tire wise you should be ok.

Also, I am not so sure you should count on the hitch always holding the 1500# on 10,000#. I only say this because of the energy created between slowing and stopping. I would think that this is sometimes less or more depending on conditions.

RV shop should be able to help you out.
