We use the TST 507 flow through system. In the manual, they talk about Michelin saying 158 degrees is the threshold where below that, the tires are OK, above that is bad, so the TST device is preset to 158 degrees for the temperature alarm. We have towed in summer desert heat and have never gotten even close to that temperature, so I would think 158 degrees would probably be a good setting.

LT & ST tires do not have UTQG grading.

Tire (running) temperatures will change from brand and design of each tire. So the only valid answer will have to come from the actual tire manufacturer.

You should be able to call one of the tire OEM providers to get someone to point you to someone that can answer your question accurately.

The listings are on page #21 in the reference below.

Great information regarding loads, tires, etc. I just completed a lot of "tire" research after a sidewall blowout on a 235/85R16 G rated Sailun. 3 years old, minimal wear, no outside storage, less than 2500 miles and had proper air inflation.
