Normal and Maximum Tire Tread Temps?

From another Forum (2010). Doug

I forwarded this thread to my contact at Michelin. Here is the response:

A tire in operation will heat up until it reaches its equilibrium temperature where the heat being generated equals the heat being dissipated.

The temperature of the tire will increase with an increase in ambient temperature. There is nothing to worry about in the ranges stated, if the temperature gets above 250 degrees F then I would be concerned !

Very interesting post Doug! I run 22.5 Michelin XRV tires my manual says to run at 75 lbs. psi on the rear axle. I found that I was getting rear tire squirm at this PSI. I experimented from that point on changing tire pressures every time I went out on a RV trip. I settled on 100 lbs psi all around worked for me best. I've been running at this lbs. psi for over 12 years now with success and I'm currently on my second set of tires all around. 10-42, I found your post very interesting also I had no idea tire pressure increased to those amounts!
