Tire pressure on the road
I have a new Mobile Suites with 215/75R/17.5, G114 tires. Max psi for these is 125 and with 15k pounds on the axles (weighed), I keep them at 125. I also have a tire monitoring system to keep a check...

I installed those up graded tires on my 36TK3 when the factory installed the 'G' rated tires. I used to watch the starting pressure grow to 142-146psi no matter if I started at 100, 110 or 120psi. That tire seems to like the higher pressures and stays there no matter what the outside air temps are. I had the TST monitor system to monitor the pressures and temps. The G tires I always ran at 110psi, but the H tire I was able to run at 110 and they held up great as opposed to running them at the 125 max cold.
If 110 was the proper psi with the "G" tires the same psi will apply to the "H" tire.
