What would be an accurate tire pressure for street using? Tires are 35 BFG, truck is a singlecab 77 F150 more or less always empty, 1-2 People carrying. Towing once in a while an 1 ton boat.

I settled on 36 all the way around... At 50 the truck wanted to wander and rattle your teeth.

On my 79 F350 4x4 SC with 35" BFG AT's, I settled on 38psi all the way around. Drives and handles perfect!

I usually run 10 under max on my trucks. Tire wear is even and handles and drives good. And still enough air to fill trailers and accosionally have a ton in the back.

I run mine at about 35lbs on the road and 15lbs on the trail. Any more than that on the road and the centers wear a lot more than the shoulders.

I have always found 35 psi is good with a 1/2 ton or SUV. You could probably run a bit less (30?) with big tires and light loads.

I had a Landcruiser 4x4 with a 351C, 5000lb ready to roll, fitted with 35" Mickey Thompson M/T's.

It came with them at 40psi and was awful - wandered at high speed and very harsh ride. I set them back to 22psi and it was much better. Tyre wear didn't really change.

Experiment and see what works well for you.
