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?

Unfortunately, trailer manufacturers haven't done a good job in the past with sizing the tires specified for their vehicles. The car manufacturers got it done by the 1990's all on their own. Pickup trucks, vans, and SUV's were done by 2008 as a result of the Ford/Firestone thing.
So we spend a lot of verbiage on trailers tires - and complicating the issue is that trailers are unique in that they are close to fully loaded pretty much all the time.
I think we are seeing the light at the end of the tunnel. The trailer tire manufacturers are changing their tires to bring them up to snuff, and trailer manufacturers are doing a better job of sizing. Hopefully in 10 years time, the discussion about tires on trailers will be closer to what we see when talking about passenger cars.
