I'll keep the brand out of it until pressed for it.
There is the ST235/85R16E rated at 3640# @ 80 psi.

Apples and oranges comparison. ST tires gain load capacity by giving up speed rating (65 MPH maximum) relative to LT tires.

Sorry but load range has nothing to do with speed. In the ST tire the speed restriction is a result of the tires design. Load range is a measurable factor in all our tires. In the LRE it is driven by 80 psi and (g) if you must.

Manufacturers may also put a speed restriction on their tires when used in different conditions. The normal speed symbol for the Michelin XPS Rib tire is a "Q" which is 99 MPH but when the same tire is used on a RV it is restricted to 75 MPH. (That can be confirmed by references in the Michelin Truck Tire Data Book).

From the Discount Tire website regarding ST tires:

Quote:
Speed
  • All "ST" tires have a maximum speed rating of 65 mph.
  • As heat builds up, the tire's structure starts to disintegrate and weaken.
  • The load carrying capacity gradually decreases as the heat and stresses generated by higher speed increases.

And that's an excerpt from the design characteristics of the Special Trailer Tire. Most will not reference it because Carlisle is not very popular because of their high ST tire failure rate.

The point is that, as an engineer, I can design a given tire for a higher load or rate an existing tire for a higher load if it only has to survive at 65 MPH versus 75, 99, 112, etc. MPH. It's a design tradeoff. So, yes, there's a relationship between speed ratings and load capacity.

On today's market a tire sized at 235/85R16 LRE can have a maximum load capacity from 3042# to 3640# when aired to 80 psig and fitted to an RV trailer.

I cannot find a single tire in the Primewell PA100 line-up that will match your description. You can go to the Peerless Tire site in the site referenced below. Peerless is the distributor for the Primewell PA100.

I got the Michelin XPS Rib and love them. I had a lot of trouble with the Goodyears that were on our fiver. I liked them so much I had the dealer move them to our new fiver in Jan. The Cameo had Duro something I never heard of from China.
