Ok, so temperature is a tire killer, and if your tires are under inflated the temperature will rise. This question is not about pressure. What is the maximum TEMPERATURE that your tires can attain before they are cooked.
I carry an infrared gun and occasionally check bearing and tire temperatures with it. I have seen drive tire temperatures as high as 150 degrees on a hot day on hilly terrain. Trailer tires usually run from 100 to 120 (the higher temp on the sunny side). Bearing hub temps usually run 10-20 above ambient.
Does anyone else have temperature data?

1000 degrees. Did you ask the tire manufacturers? You can contact them via the internet or by telephone. I am certain the can give you an accurate answer. Let us know what you find out.

200 gets quoted as where damage starts but I would consider any tire hot from running very low or overload to be trash.

I would think that curvy roads would do more to raise tire temps than hills. It's when tires scrub that they create more friction that causes temps to go up. I do know that race tires will raise a near-instant blister if you touch them right after they come off a car (NASCAR, Indy, F1, etc.).

It's not a constant. Heat kills tires but they don't just burst into flames so a set temperature is meaningless. Keep them properly inflated to CONTROL over temperature and that's all you can do so worrying about something you can't control is pointless.

One tire with significantly higher temp over the others would be a red flag.

With several years behind me tow while using an infrared heat gun, all 8 tires on the ground range from 115 to 125 degrees. Rear TV tires normal run the hottest at 125. High wind from the South had my North side trailer tires running hotter than the Sunny South side this spring on the run from Phoenix to California this spring. The XPS RIB all steel ply tires on the trailer normally run about 5 degree's less than the TV. Rear slightly warmer than the front axle on the trailer.
I would think that most ST's with they soft sidewall and baseball shape would run hotter than a good LT tire.

I was told that a temperature of 155 degrees F was a good warning threshold. I have seen 145 on a hundred degree day at fairly high speeds. I would be alarmed if I saw 160 degrees, and you CAN do something about it, like slow down or even park for a while.

My truck tires sometime reach 150 degrees in South Georgia/North Florida during the hot summer 97-100 degree days. Trailer tires were about the same. In the winter, of course not really cool here but around 69+ degrees ambient, the same tires run about 120-125. I mostly travel 65-67 mph towing. I always check at rest/fuel stops with a Radio Shack infrared thermometer. I always look for one tire or hub several degrees above the others as a danger signal.

I check mine at every stop with an infered gun and my 5th wheel tires run between 110 and 120 on hot summer days and the truck tires run 115 to 120 for rears and 110 to 115 on the front. I drive around 60-62MPH with the crusie on. I have never seen more than 5 degrees difference between the tires. I also check the wheel hubs and they run a few degrees cooler than the tires. I figure as long as the temps are consistant across all the tires then I am good. If I should see a large difference then I would suspect that I have a problem. I even had a truck driver tell me that I was the first RV'er that he had ever seen actually checking my lug nuts with a torque wrench and checking tire temps.
