[C&P RV]

The TST monitor comes with the high temp alarm set to 158 degree (F) and they specifically recommend you not change that setting. They recommend setting the high pressure alarm at 125% of the rated inflation (110 psi for Sailuns so the alarm should be set at ~137 psi).

We just returned from 30 days on the road from Texas to the east coast. We were blessed with very nice weather for most of the trip, but for our last 2 days the air temp was near 100 by mid afternoon along I-10 in LA & TX. The tire temps were reading ~145 and I confirmed that with an IR temp gauge at rest stops. Pressure was hovering around 125 on all 4 tires which started out "cold" each morning at 110.

We had a crosswind and the tire temps on the side away from the wind were occasionally higher because of the pressure on the windward side of the RV from the 20 mph winds.
