how to set tire pressure when ambient is 115 degrees

[gargoyle999]

Thank you for asking this! We just completed a 3600 mile trip in our brand new 2016 Grey Wolf and I was wondering the same thing (first RV!). Temps ranged from the upper 30's to low 90's during the trip. When starting out from home I set to max 50psi (low 80's temp) but psi would be low 40's on the colder mornings. I was using a TPMS (the TST mentioned above) and did notice the pressure would increase to mid 50's once driving so I just left it alone.

Thanks

Our Silverback was purchased in late October, 2014.....Tires came filled with Nitrogen....When I installed the TPMS last week, they were reading about 70 psi....I filled them to 80 psi with my 12V air compressor....nothing but straight air went in and I then installed the sensors.
