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 run the same cold tire pressures as RustyJC in our tires, 120 PSI. We took a trip last July to Oklahoma to see my dad and saw pressures increase to about 145 psi in 100* temps. I don't recall what the tire temps got to but all was fine. I run the TST TPMS.
