Tire Pressure
What's the consensus on Max tire pressure when towing 10K. Generally I run max tire pressure as rated on the tire for both the trailer and tow vehicle, with the exception of the front tires on the ...

If you run more pressure than the load calls for it can wear the tires out in the center faster than the edges. I had that problem on my 2500 Suburban. The tires are rated for 80 psi. The door placard calls for the rear tires to be 71 psi. I was running them at 65 psi because I know I'm not near max axle weight. The rear tires were wearing out in the center so I lowered it to 55psi.
According to the load inflation table that's all I need to carry the weight I've got on the rear tires so that makes it the proper pressure. Running 80 psi would be an incredibly harsh ride and wear the tires out worse.
You need to weight your axles, consult the chart, and inflate accordingly. Any other method is a guess and likely wrong.
I never worry over much about how rough the ride is for my trailer. I know the enemy of tires is heat. Tire flex makes heat. And I know that a tire inflated to max pressure will flex less than one set at a lower pressure for any given load. Will the underloaded/overinflated tires wear in the center? Likely, but who wears out the tread on RV tires?
And before somebody goes into a rant about the damage the rough ride might do to trailer, look at the damage a blown tire does.
