Trailer Wheel Ratings?

Wheels on every hard sided TT I've owned (three) have had rating stamped on rear, or in valley under the tire.

Note inflating a LR-E tire fully on a LR-D rim is a TWENTY THREE PERCENT OVERLOAD. Some call that safe I guess, but I do not!

I just bought a set of Maxxis tire from American Tire for my 5th wheel. They also tried to sell me load range E. When I told them my rims not rate for the higher pressure, they ordered load D and they were $30 each cheaper. If you get load range E,you can't carry anymore weight because your still limited to rims and axles ratings. Also running a tire at lower pressure can cause it to run hotter.

My new TT thaT weighs 7400 lbs DRY came with load range C tires. It now has load range E Maxxis.

My wheels were not stamped with a psi rating, but were stamped with a weight rating. With that I was able ascertain that the wheels were good for use with a G-rated tire, hence 110 psi.

Rim weight rating and tire PSI are different factors. I doubt a reputable tire shop would mount an un-safe combination.

My old ones had a weight rating stamped on the inside of the wheel, on the back of one of the spokes. With the weight rating you can gather the PSI it will withstand.

From what Discount tire told me as well as Les Schwab, rims are no longer stamped with psi ratings. A good place to look for trailer rim ratings is herehttp://www.tredittire.com/Steel-Wheels-C11.aspx.

Find your rim size then look at the weight rating, then find the tire to match the weight rating. That tire will have a psi listed for it.

My trailer came with a 225/75 15" D rated tire and the rims were rated for 75psi hope this helps some.

I think your rims will be just fine with E's. Enjoy your new tires.

Conventional wisdom is the rating is stamped on the wheel on the back side or under the tire. I have not found mine so I suspect it is under the tire. Even if your wheels are only rated for 65 psi (D's-likely) taking them a few pound over should not pose a serious risk. The "E's" are rated at 80 psi and can carry a lot more weight. I have considered upgrading to "E's" on my next purchase for the reserve capacity and running them at 80 psi.
