I was curious to know if any of you have the TPMS sensors on their trailer tires and what you have your warnings set at. Without getting into the debate of the ST/LT tire thing, I would like to know w...

Running your tires at max cold psi will keep the operating temps lower-
You have two things at work in a tire- pressure and heat. Running ten pounds lower than max will have a dramatic affect on the operating temp of the tire- especially when ambient air and road temps are high.
In my experience- Tires come apart for two reasons. They hit a road hazard that causes a catastrophic failure or they fail due to heat. A nail, while certainly a road hazard, does not cause the tire to fail. It is the loss of air and subsequent increase in temp that causes the big blowout.
Keep your tires at max cold psi and you will have fewer tire failures and your tires will last longer because they will run cooler.
