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?

Tires are designed to allow for increased heat and pressures no matter the inflation as long as the weight and inflation are applied properly. Poor reason to run 95. If there are other reasons as that is the proper pressure for the load that's fine.
True points. However, I ran 3 brands of tire on the recommended 80psi on factory supplied aluminum rims. 1st set from OEM I changed after 1 year as they were showing excessive wear. 2nd set were Continental the dealer recommended. Tire tread separation after 2nd year. 3rd set were Goodyear Marathons and a tire tread separation blowout did severe damage. Ran all 3 sets on TPSM at factory recommended 80 PSI. All 3 registered over 96 psi and 112-115 F on the highway. The factory aluminum rims were rated at 2900lb. Max for trailer when loaded. Switched to steel rims rated at 3500 lb and Sailun's. Tires run at an average of 105-109 PSI and temps in the same range.
