PSI Question

I have no idea what my PSI should be, I have a 2012 F-250 crew cab 4x4 with Firestone Destination A/T 285/70/17's on it, people are telling me conflicting things, max pressure says on tire 80. Thanks in advance!!

You can run max pressure on the tire if you like. It will be a stiff harsh ride. You can also look on the door label for Manufacturer's suggested vehicle tire pressure.

ford puts the max PSI as the normal reading on the door jams. Which is 50psi front 80psi rear...I run 80psi in the rear when I tow or haul regardless if it's my 450cc dirtbike or I'm hauling two yards of mulch dirt. I run 50psi in the front at all times, I've tried running 40-45psi in the front and even with Elias tires the front end gets "leany" in turns so I just stay at 50psi. I will say I felt no difference at 40psi or 50psi in ride difference, handling better with more psi

Follow the door sticker if it's the same size tires and less than or equal to the tire sidewall max.

I'm at 75psi on all four corners.
