I'm curious as to what you consider the correct psi, to put into your trailer tires? I have a toy hauler, 28' twin axle. Fully loaded i'm 15 - 16K lbs. The max rating on the tires, is stated at 80psi. I've always pumped them up, to 75psi. Giving me a bit of room for pressure increase, due to heat. What do you guys think?I have a buddy, that has a very similar set up, and he only runs 50psi. His tires have the same max psi as mine. Is this ok too?That are your thoughts on this?Thanks, Joe

Check your owners manual to certain, but typically you run the trailer tires at the max psi listed on the sidewall.

There should be a sticker on your RV somewhere that tells you exactly what you should run them at. My recommendation would be to follow that.

Tire and loading sticker on the left side, in front near the bottom. PSI is cold pressure, if it calls for 80 PSI, put 80 PSI in when cold. 75 PSI would be underinflated. The given pressures already take into account any pressure increase from heat.

Max psi on sidewall is for max weight rating.
Every tire mfg has psi to load chart
