Where to Find Rim PSI Rating


How do I know the psi rating on my rims. I have stock aluminum wheels on my 2015 37 ft 5er. Only thing stamped on the Rim is a 22 and nothing that indicates psi. The towmax tires have a max psi of 80


Expert Reply:

If you pull the rim off there should be a sticker or plate that has more information. It looks like the picture you submitted may be from the inside of the rims so you may have already looked for it.

Typically trailer rims are rated for the PSI of most of the tires that are available for the size. There is a good chance your rims would be just fine inflating your tires to their max psi.

If you can find a brand on the rim you can try contacting the manufacturer as well. I am not sure what the 22 means on the rim. But it would not be the psi rating.
