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.

This is exactly right. Heed the advice.

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.

You see it does not natter what a GY Tech told me or my long time experience using weight/inflation charts with excellent results. What does matter I guess is what's cut and pasted .
"Unless trying to resolve poor ride quality problems with an RV trailer" this is what a person is trying to do running a heavier load range tire because an 80psi "E" tire running within it's capacity is fine but changing to a "G" tire at 110psi is going to give you "POOR RIDE".
