I know this is a ridiculous question. What is a good tire pressure to run on a 03 fx4 supercrew? I have them at 35lbs, tires say 44lbs max.

 

I know that's what I run on my 01 4x4 Screw.

 

I have them set to door spec but man they look a little low to me. I was thinking going to 38-40?

 

Could also be that I went from an Michelin at2 to a continental... Totally different tread design

 

I run 45 in my Nittos to make it feel right

 

It depends heavily on what you're doing with your truck, and what you want out of it. I generally run 60psi in mine, but thats with Load range E tires. You have to decide what you want in terms of traction, handling and gas milage. I'm happy with the ride at 60, and it can take a load without having to air the tires up.

 

I run 38 in mine
