Tire pressure and temps while towing
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...

I have also noted on both trailers I have towed with the TPMS system on them that the curbside tires will run about 3-4 psi and 5-8 degrees warmer than do the drivers side tires and that's based on starting with 80psi all the way around.
I did contact Maxxis on this and all they could tell was that the tire was designed for increased pres and temps and as long as I didn't exceed the weight rating of the tires I shouldn't have any issues.
Maxxis tire tech line isn't much help where tires on a trailer are concerned. This is where a good experienced truck tire dealer has more hands on experience of what works best vs what works on paper.
Anyhow I've seen my LT235/85-16 E tires on my equipment trailers running max loads in 100+ degree outside temps go as up in the 90-92 psi range when on a long run on the interstate. Even though the ST has those rounded flexy sidewalls it may run about the same psi gains. I have no idea of my tire temps.
