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?

I'd keep them at the 110 psi that is indicated on the sidewall. Under inflating will cause more sidewall flexing which = more heat. Of course you can run them at any psi you'd like, but I kinda trust the engineers that designed the tire and say run 'em at 110 psi. That's what I run my S637 ST235/80R16 LRG Sailuns at on my 15,500 rig.
