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?

They would probably be fine, but that just seems too low for me.fj12ryder wrote:wilber1 wrote:Actually yes they are recommended pressures. Per Goodyear's RV's Tire Care Guide: "Inflation pressure should be adjusted to handle the tire carrying the heaviest load, and all tires on the axle should be adjusted to this pressure."

Load inflation tables just tell you how much load a tire can carry at a certain pressure. They aren't recommended pressures.
This is also in their inflation guide.
Tire pressure should never be reduced below the vehicle manufacturer's recommended levels to support load conditions in order to improve the ride quality of a vehicle. The difference in ride quality is not significant. When minimum inflation pressure requirements are not met, tire durability and optimum operation can be affected.
