I just mounted new Sailun 235/85/16s. Should I run 110 PSI or 95 PSI. I got both opinions at the tire store. I'm in Tucson and we get hot - does that make a difference?

Weigh your tires separately if possible. Use the weight/inflation chart for your tire size and load range. Add 5psi to what your chart says. This is per GY Tech support. You will get some nay sayers on here but I have towed many thousands of miles using inflation charts on vehicles and RV with great results. Better stopping, ride and tread life.

I have Sailun S637s. I run 110psi despite the fact that I have "only" 2600lbs on each of 6 tires.

Advise from Goodyear officially comes from their websites "weighing RVs" which follows advice from tire experts like Tireman9 and a host of other website blogs on proper tire pressures for tire in a trailer position.... ;
Goodyear Tire and Rubber .... weighing RVs
Special Considerations
** Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load carrying capacity and minimize heat build-up**.
Of course Goodyears and tire experts thinking is the trailers tire selections were per the FMVSS regs...not a rv rookie severally over tiring the trailer to the point of having to derate the tires sidewall pressures/best sidewall stiffness.

Lots of opinions concerning tire pressure! You can use the charts, using actual scaled wt on tires, keeping in mind these charts are giving a minimum psi to support that wt. Tire engineer experts say (in regard to trailer tires) "if using the minimum chart psi, you must add a minimum of 10% more psi, as a minimum." Then they suggest 20% above chart number better yet. Now if you have the proper tire for your trailer wt, using full sidewall pressure works best.
Generally speaking, for trailer tire temperature, even in hot climate, is to use max sidewall psi for coolest running.
