Goodyear Tire and Rubber .... weighing RVs
**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,**
Now if you've done something silly like over tiring a trailer to the point max pressures cause a harsh ride or pounding the trailer or the tire is riding on the treads centers (verified with a chalk line across the tread) then you may have to derate the tires pressure.
The advantage of a E tire from a OEM D tire comes at 80 psi.
