Tire Pressure

What tire pressure are you guy's running. I have Toyo's 255/85/16. A tire shop said that when not towing or hauling that 40PSI is perfect for ride and tire wear. What do you think?

Should be running 45 front and 40 rear unloaded and I wouldn't go higher than 50 when towing (in a proper E rated tire). You're going to kill your ride going higher than that.

I am running an E rated tire and with my bilstiens and 65psi my ride is just fine. I think from the factory on the sticker in the door, these trucks call for about that anyway.

So it seems for a 4wd F250 SRW:

80psi rear =3415 lbs per tire x 2 = 6830 lbs (your rear axle rating)

55psi front = 2600 psi per tire x 2 = 5200 lbs (your front axle rating)

Is what the factory calls for with stock E rated tires.

I am running Bilstiens and I have had it at 65 and was a really stiff and bumpy ride. I lowered it to 50 on all four yesterday and was amazed at the ride. Very nice. I'll try that 40 rear and 45 front and see and re-post. Don't want to shorten the life of my Toyo's at $1200 a set. Thanks for the info.

I run i think 65front and 72 rear. that plus rotating the tires every 5k has kept nice even flat wear.

I may lower them for my trip to VA beach this weekend and see how my mileage does.
