Does the Rim or the Valve Stem Determine the Maximum Pressure

Question

Question:

I have some trans eagle 16ply tires that hold 115 psi and I have 16” rims with all metal valve stems on my dump trailer. Is there any 16” rims that aren’t capable of holding that much air or is it the valve Stem that really matters in this situation?

Rims like the Aluminum Split Spoke Trailer Wheel - 16" x 6-1/2" Rim - 8 on 6-1/2 # AM22659HWT do not have a psi rating. Like you said, it is the valve stem that will be the limiting factor for tire pressure. For example, the Americana Metal, Bolt-In Valve Stem # AM20906 is rated for up to 200 psi where the Americana Rubber, Snap-In Valve Stem # AM20903 can only hold up to 65 psi.

Hi Rob! We definitely have 13" wheels with the 4 on 4 bolt pattern and 185/80R13 tires, but we do not have any already mounted, unfortunately. The 4 on 4 bolt pattern isn't super popular with the 13" wheels for some reason, so you will…

The same dynamics for passenger tires are not applicable for trailer's. Therefore, I do not recommend using a smaller tire on your trailer as a spare. The spare tire on a vehicle is mainly designed to get you to the nearest repair station. The…

I spoke with one of the engineers at HWT and he told me that the psi rating for an HWT wheel and tire assembly is only limited by the valve stem and tire. If your current wheels or new wheels have a psi rating under 110 psi, it is okay to use tires…

We do have a solution for you but you are going to need to know your wheel's bolt pattern in order to get the correct wheel. Since you mentioned you had a 20.5x8.0-10 tire (which is the same size as a 205/65-10 trailer tire) we know you have a…

Generally, I do recommend that all tires on your trailer be the same size at all times, so ideally your spare will match the existing tires on your trailer. With that being said, the difference between a 175/80-13 and a 175/80-13 tire is only 0.3 of…

Answer 7

It is usually the tire valve stem that matters when upgrading trailer tires to a higher load range that needs higher psi pressure. A bolt-in metal valve stem like #AM20906 handles pressure up to 200-psi and it includes two grommets so that it will…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 11

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Answer 12

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
