How can one determine the max psi rating for a Ford 14 inch aluminum rim?

[deadwood]

My trailer came with crummy black steel rims and hubcaps (14'' 5X4.5 6" wide). My neighbor has some nice looking Ford aluminum wheels identical in size to my crummy black ones. My question is, how can I determine what air pressure these wheels are rated for? I looked on the back of the rims, and this info is not shown anywhere. I hope to put new tires on the rims (if I buy them), and the new tires require 65 psi. Thanks

I was always under the impression that the rims could handle any pressure placed on them, and that the tire itself was the determining factor on PSI. I would imagine if you follow the manufacturers stated pressure for the tire you would be fine.

agree^^

Not sure if they have ever been required to have a test.
have a gooseneck stock trailer that is supposed to have the best load rated trailer tire going. after a few years a couple of them developed a slow leak .. turned out the wheel was where they were losing air.. The max inflation of the tires was 120 psi.

Fill it

I’d check the offset of those Ford wheels. I doubt they are going to work, but maybe.

I had an old trailer that came with the Hydo-sport boat I had, that had Ford station wagon wheels ( back in the late 70's ).

Not true. Rims have a rated pressure and it's often less than 65psi.

Where can these be found ....
I've had many different truck and trailer tires that require way more than 65 PSI

My aluminum trailer rims are rated at 60psi. Stamped on the back side of the wheel. Made by Ultra Wheels.

The one I found a few years ago off of a Ranger truck were "0" and it was marked on the back.
You will need a "0" offset.

Interesting !!
The link says --

All wheels are rated for maximum load and inflation pressure. These ratings must be compatible with the tire ratings---If ratings are not marked on the wheel, check with the vehicle manufacturer and the wheel manufacture

I just checked several units and was unable to find a PSI rating --- did find a load limit rating on my boat trailer and that it's made in Korea.

You would think they should be tested and marked..

You would think. It would cost money though, and some idiot would probably inflate 35psi tires to whatever the rim said and end up suing the manufacturers.

60 PSI sounds kind of light-- As I recall- Good Year put out a bulletin several years ago when they were blowing so many Marathon SP tires. Stating to run over 65 MPH you need to inflate them 10 PSI over the max which was stamped on the sidewall.

Then want to sue !!
