Heat. How how hot does everyone allow? Tire heat sensors?

Tire pressure and temp sensors are new enough lots of trucks don't have them and many drivers don't have experience driving with them. Only my last truck had the TPMS. I'm not sure I would stop driving due to the tire temp. But I haven't thought about it before. I'm looking forward to the rest of this thread to see what others say.

 

Nitrogen is the ticket. Builds heat less then regular air…. But good luck finding it at a truck tire dealership.


I always slowed down when it was really hot ……

 

The trucks I drove were all mechanical, no electronics. So the hotter it got the slower we drove. Those tires will get so hot you can't touch them. Run it cool.

 

What happens to "Wind Chill" during the summer?

 

I did some Googling and found several sites that said that tires don’t degrade until much hotter than they’ll get even on the hottest days.

Example (from Bendix):

“Most experts consider 195 degrees Fahrenheit as the “line in the sand” when it comes to tire temperature: Beyond that point, the temperature will start impacting tire life. At 250 degrees, a tire will start to lose structural strength, could begin experiencing tread reversion and the tire will begin to lose strength.”

 

I've seen that tread reversion. Just last month.

 

Woke up in Wisconsin. It was a bit chilly

 

Heat index and windchill really only pertain to living things. However, there is an effect on mechanical things.

Turn off your truck in -10 and your engine will be warm for a while. Same thing with a 40 mph wind and itll get cold much faster. Take a water pipe and run it into an unheated, drafty building. In a 40 mph wind the part thats outside will freeze before the part thats inside. Wind saps residual heat from everything.

As for heat index on inanimate things I think it’s more about solar radiation which is different. The sun is hot, very hot.

 

Well, it's called a "wet bulb thermometer", the bulb is surrounded by wet fabric. You take the wet bulb temp and the dry thermometer temp, then consult a chart which gives you the "heat index" (or you can use a phone app to figure it out).
