Max PSI *while* on the road?
I see all sorts of discussion about PSI and cold/hot temps, etc. etc but here's what I can't find... I'm using RVIBrake's Tire Patrol and my cold pressure was set at 100 (which I might lower towards 90 after I get a good weigh-in, but that's a separate conversation!)
About 4 hours into the drive, RVIBrake alerted me that my right rear interior tire was hitting 120PSI. However, the temp was only 80F on the tire. Everything else was around 112-113.
I slowed down for a bit, it slowly went back down around 116PSI.
What is a PSI that I should be worried about, if temp is low? What does everyone dial their TPMS sensors in for alerting a high PSI?
