The max tire pressure on my 16" E rated tires is 80lbs. My truck is 2WD. I am towing a bumper pull Toy Hauler with WDH and near GCWR. What should I run my rear and front tire pressure at?

Not a lot on info here gn what you are driving and the various weights of things, but if it is a late model truck, I would start with the tire size and pressure chart on the door jamb of the driver's door.

I guess you are referring to the truck tires. On my last F 250 65 in front and 80 in the rear worked out with an 1800 pin weight.

As Pete says it depends on the size of your truck. E tires can be put on a half ton/three quarter ton or a one ton DRW truck. Even a gas vs diesel engine makes a difference in air pressure requirements for the front tires.

Your door post should tell you the correct inflation pressure for your truck provided your load range E tires are EOM on the truck. The inflation pressure on the DOT safety plate is what is required to handle the GVWR of your truck. For example, my F 150 has OEM load range E tires and the recommended inflation pressure is 55 PSI front and 60 rear for my 8200 GVWR truck.

It is also a good idea to know what your weight load is on each axle while you are hooked up. You may not need to run your tires at Max recommended psi if your weight is not at that etched on your tires.

Pressure will of course depend on loading. After weighing, I was surprised to find out how much heavier my truck was than I thought it was (with the TT attached). I added air to all four tires and improved the handling considerably.

My truck is a 1999 2 WD F 250 Super Duty with 7.3 and Auto Trans 3.73 rear diff. The truck as a upgraded 6.0 Trans Cooler and rear Air Bags.
The last time I weighed I was a little over in weight due to max water (80 gallons in the fresh water tank) and gear in the bed of the truck. I usually just run about 10 gallons of water til we get where we re going. My weight is normally pretty close to the sticker weight ratings. But this particular time I wanted max water to see how much I weighed.
Weighed in with trailer
Front axle 4050
Rear Axle 5500
Two trailer axles 10,650
Door post says 8800 CVWR
Front 4550
Rear 4970
Front psi 50
Rear Psi 60
My E rated tires have a max pressure of 80 psi
So should I go by what the door post says or get closer to the max psi rating on the tire?
