tire pressure
just had new G rated Sailun tires put on rig. These tires are rated at 110 psi Our rig weights around 19,000 lbs Am I okay to keep the psi at 90lbs or should I always keep them at 110 psi?

Those S637 are tough and can take lots of abuse such as derating with low pressures. Glad you didn't see a reduction in mpg like the silly guy with the H S637's. Your the man.
Goodyear still has the same recommendation of max sidewall pressures for trailers with a unless clause.
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.*
