Just went to the Duro tire web page, and they do not even list an ST tire, just several different LT tires, and the only ones in 15" are 7.00X15 bias ply. That could be why your tires are not restricted to 65 MPH. Tires | Duro Tire & Wheel

Interesting. Those Duros (the ST in 10 ply 15") look visibly different than GYMs to me. I couldn't find speed rating info (not the most navigable website but I'll keep looking). It wants 80 psi for those - if they ran at 65, would that derate the 2800# capacity per tire and/or would they run too hot?

Thanks!

The Feds have an imposed publishable speed rating on ST tires of 65 MPH. Some tires may do better.

Not exactly.

The Tire and Rim Association - a US based tire standardizing organization - is the one who created the ST tire designation and the 65 mph limitation is a part of the standard they published. While the federal government recognizes the standard, it doesn't require compliance - although any tire manufacturer would be foolish to deviate from the standard.

Some trailer wheels cannot take 80 psi of pressure, just a note. Jim

If I am not mistaken the 65 MPH limit on ST tires isn't the max speed rating of the tire, it is that all ST tires are tested at 65 MPH max. What a given ST rated tire will do at speeds in excess of 65 MPH is an unknown as the feds only require the tire manufacturer to test up to 65 MPH. My understanding is this isn't a speed rating, rather the speed limit of the test for that tire type.

Ah ..... not exactly. You're ever so close.

First, it isn't the federal government that is impossing the limitation, but they recgonize the tire industry standards as published by The Tire and Rim Association, and mandate that the tires pass the test appropriate for the standard. And, no, the test speed is not 65 mph. I always struggle when I read the regulations, but if I have this right, the test speed is 50 mph - BUT - the tire is tested at a lower pressure. Because speed and inflation pressure can change the result of the test, you have to be careful quoting just part of the test conditions.

OK I knew it was something like that, hense the way I started the post. And I was pretty sure there wasn't a federal mandate that stated ST tires were only good to 65 MPH.

Thanks for the clarification.
