I saw a post on an RV Forum about a tire "Blowout" on an RV that had a TPMS.
The RV owner said they had TPMS but still had a sidewall failure. He also said, he "set his "baseline" PSI which is the threshold for the low end pressure reading and then the upper limit alarm will tell you if you''re exceeding normal pressures and headed for a blowout. Same thing for the temperatures as well....set the baseline and then it alerts you if the tire temperature is above normal and too high. I used my unit last year on 2 long haul trips to MI and it performed well. Gave me the piece of mind knowing I could keep an eye on the tire pressures and temps. I do recommend the unit. I purchased the unit which can support up to 22 sensors, but got the TPMS system with 6 sensors on Amazon, then bought 2 additional sensors for a total of 8 - 4 for my TV and another 4 for my TT. My trailer has dual axles. I mounted the wifi extender on the front of my TT just behind the battery box and use the clip on leads from the battery to power it. The wifi unit is in my truck and I tuck it in the center pocket in my cab. Works well."
