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?

Are you talking double axle or triple axle? A triple axle 5th wheel will have about 16,000 lbs. on three axles or around 3,000 lbs. per wheel. I run about 2500 lbs./wheel on my triple axle and inflate to around 90 psi. A double axle 5th wheel should probably be run at the max sidewall pressure.
Max pressure is required for max carrying capacity. Not max carrying capacity, you can run less pressure if you so desire. Over 5 years and 20,000 miles running my Sailun at 95 psi and they still look wonderful.
X2. 2+ years of running at 95. FIL has owned and driven a commercial dump truck for 50 years including pulling a tandem dump trailer. He and his tire guy both suggested 95 max as tires gain PSI once they have been up to highway speed for a few miles. These tires also run cooler than any of the previous 3 brands.
