Recently installed a TST 507 Band style. Making a 3hr trip the other day and outside temps were 82* and inward running 73MPH. The sensors were reading on the right side of 140*/100psi on the rear and 138*/99psi on the front. The right side was ranging from 12*-15* cooler and psi was in the mid 90 range. Right side of the trailer prolly weighs a little more so I can understand the difference right to left.
I'm guessing mine are going to read a little higher since mine are band style around the center of the wheels and there will be more heat there from the bearing spinning and maybe even a slight brake pad drag since I got disc brakes.
The trip home tomorrow will have outside temps in the 90's so this will be interesting where things run at. Past years I've run the same speeds, same 80psi cold, and same weights and never had any issues, BUT I've never had any data to know what my tires were doing. Now I do and dont have anything to gauge it off of.
Just wondering what other TMPS users have and what your reading are?
sunny side is always a bit higher. I carefully checked mine before before installing and pressure was perfect when installed but always a little higher on sunny side.

I can go along with the sunny side being higher. Makes perfect sense. Before I left the house tire temps were pretty close to outside temps and PSI's were all at 80, +/- 1.
Funny thing is i was headed west which would put the higher temp and psi right side tires on the shaded north side.
Have you guys seen tire temps and PSI as high as mine before?

I have been over 96 psi after having set my tires at 80 psi at 72*.
TPMS went off as I was passing a semi. Scared the crap out of me since I thought I blew a tire. It was because the outside temp reached nearly 100* and as a result the psi went over the 20% upper limit on the TPMS.
I also notice temps on the opposite side of the wind direction. Probably the tires are carrying more load due to the wind and the high wall of our FW.
I have noticed my right sides often run warmer than the left. Since they sun wasn't always a factor in this and my bearing temperatures seem to be the same on all 4, I have come to the conclusion, that my truck exhaust my be affecting the higher temperatures readings??
