Tire Temperatures
Well.... interesting observation made today. After my last tire failure, I had quite a bit of damage in the fender well. We took the coach to Camping World today (about 60 miles from home) for an es...

Temping your tires one time will not tell you much or after 60 miles, or five minutes after stopping. After several hundred miles some of the variables from your baseline are:
On a cool day or if running in the rain your temps can be 10+ degrees cooler than normal. Rarely are the front and rear tires the same temp. The bottom of the grove in the tread can be 5-10 degrees hotter than the tread. Almost always the inner dual tire will be hotter than the outside, as much as 10 degrees. On a hot afternoon the tires with the sun on them will be hotter than normal and about the only time the dual on that side will be the same temp. A strong cross wind will add 5+ degrees to one side and take that much from the other... a pretty good reason for running 5 psi over the pressure for your load.
Until you temp your tires enough times to establish a base line there are too many variables to let even a 10 degree difference bother you. I agree the smaller Bridgestone MAY explain the difference but not after 60 miles and one time.
I temp the sidewall about 1" from the tread as that is the easiest place to get to on the inside dual tire. This will be about 10 degrees cooler than the bottom of the groove in the middle of the tire... the hottest spot on my tires. I started temping my tires ten years ago, long before I have a TPMS and still do but not as often.
OP, do not let a 10+% increase in your tire pressures with your TPMS bother you as this is normal.
