What is too hot

Actually, I would STOP and check for bad wheel bearing, brakes hanging up, etc.

I’ve yet to have mine get over 120 even on 95+ degree days! Not sure what the temp is, but if they hit 150 I would be slowing down!

I measure the parking lot temp as well as the tires. No point getting worried about tread/sidewall temps of 140-150 if the sun has the surface at 140+ degrees on those 90 degree afternoons.

My TST sytem will alarm at 157 degrees, have had it go off once on my truck when a brake pad stuck and got the brakes too hot radiating into the wheel & tire. Let me know I had a problem that I was able to fix. Highest I normally will see in Arizona during the summer while driving is mid 120 degrees.

I no longer use a tire monitor system.. I find they are more trouble than they are worth.

I use new Michelins, keep the proper inflation pressure, and coat the interior with tire slime.

I run 100 PSI and feel each tire at every stop, each tire should feel very close to the same.

no system will save you from a catastrophic tire failure, a slow leak will show in heat.

there are several tire within a tire systems investigate those options.

This is what I do. If all tires are running about the same, then it should be good (or you have a major issue). If one tire is significantly higher (or lower) than the others, then it's time to get it checked.

Googling the question says 195 to 200 F is the upper limit. But that seems way too hot to me.

I use a IR temp gun on the side of my tires near the tread… easiest place to temp the inside dual and highest temp I’ve seen is 140. Not sure of the relationship of the temp at a valve stem and the side of the tire. Have read that you should start worrying at 180 but 150 would worry me based on many years of checking.

If your tires are inflated to the proper PSI, based on a verified weight of your coach, any increase in temperature is easily handled by the tire design. If your tires are underinflated they will usually get hotter than if properly inflated.
They sell an inexpensive ($20) laser temperature gun that can be used to check your tire temperature after a run.
Some people try to avoid getting their coach weighed and try to "guess" at what the correct tire pressure should be and then want to guess how hot their tire will get. Do it right and eliminate the guessing. Your coach will ride better, tires will last longer, and you will have the best braking and driving traction when properly inflated.
