TPMS Question
I recently installed a TPMS system and was wondering what the high limit is folks used as compared to what their PSI is. So my trailer tires are at 80 PSI and noticed they went up to 89 PSI on the way...

Check your tire specs for the maximum pressure. TST indicates it should be about a 25% increase. I've seen 10% which does not include hot summer days on the MH.
I have both an internal sensors system (Smart Tire) and TST. The psi difference is 1 psi. The internal sensor temperatures range from 41 to 54 derees higher than the TST values. I attribute this to the TST sensors being mounted outside the tire on brass valve stems and rotating itn ambient air. In other words external sensors have significant lower temperatures than the actual tire temperature.
Stopping and quickly measuring the tire sidewall tempeatures resulted in values 6 to 26 degrees below the internal temperature.
