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 tow vehicle I run about 5 lbs under max tire rated pressure because I think the front runs a little light when towing.

The pressure that gives the tire its max weight capacity.

Weight the axles and set the pressure according to the tire mfg load inflation tables.

I've often weighted at the free OR scales.

I tow 19,000 pounds and don't run max air pressure, never have. Air pressure is a function of weight being carried. If I'm not carrying max weight then why run max pressure?

My trailer tires have best wear pattern at 70 PSI. My truck sticker says 70 up front and 65 in the rear duallies. It's what works for me.

I have always ran the max psi on my trailers whether a fiver or tag. I have never had a problem with doing that. As far as weighing each side or each tire some do some don't. I fall into the latter group. Tires run cooler at or near max psi. Just my opinion.

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.

It will probably depend on the tire size, the rating, and actual load on the tire.

Running max pressure unnecessarily can result in a very rough ride.

I spoke with a Bridgestone engineer a few years ago about tire pressure. Engineer said to run tires at max (cold) air. He advised running max air will eliminate possible blowouts. Just do not go over weight rating for tires. I also asked, if I run max air, will the tires blow with they heat up while driving. Engineer said tire will not blow. The tires are built to handle the max (cold) air.

I run load and inflation table pressure. Sometimes that is “max psi” depending on the load.

If you change tire load index or size from what is on the sticker the sticker no longer applies.
