As far as I understand it and according to Google;

What temperature is too high for trailer tires?

I usually recommend setting your TPMS to alarm at about 158 degrees Fahrenheit. If you have a tire position that gets to this level, then you likely have a problem. Setting it at 158 degrees Fahrenheit still gives you time to get off the road before damage is done to your tire because of the climbing heat.


My GMC is preset and has a built in TPMS system. I see 130 degrees in the summer at 110 PSI and 95 deg weather. It's still green. I don't think I've seen the pressure reach those levels. I want to say 115 PSI maybe?


More from Google;
If you check your tire pressures in the morning with temps in the 70's then head out across a desert where temps can be 110-120 degrees your tire temp can rise to 130 degrees or more. The average tire will gain around 5 psi, well within the design limit for a tire.
