Why Dont Trailer Wheels Normally have PSI Rating Listed

Question

Question:

On all the trailer wheels you have for sale, none of them state the PSI rating for the wheel. The max load rating in pounds is shown, but not PSI rating. I just want to make sure the wheel I buy is rated a higher PSI than the tire I am going to put on the wheel. Would like to see the PSI rating in the spec section for all the wheels.

The reason for that is because in most cases the psi limit is the valve stem of the wheel and not the actual wheel. The wheel will have a higher psi rating than the tire and the valve stem so it's usually not listed.

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…
