What PSI air pressure are your tires?

[Meeka]

I attended ford tire tech school in Dearborn along time ago and the teacher stated ford engineering can try several brands and pressures to get the best overall result. They stated on the vin label you will find the best pressure for handling and ride quality

My vin says 35 all around ‘cold’ but I usually put in 2lbs. more in front, cause they do more work than the rears, engine weight, steering etc. Am I wrong?

I my self only put in a couple pounds more if I’m going on a long trip which does improve fuel mileage due to smaller rolling tire patch to the ground.you will have to test it for yourself everybody has different driving habits.

I remember years ago checking the tire pressure on rear wheel drive, smoke the tires a little, check if the ‘ black patch’ was smooth all across and adjust accordingly. Little patch, too much air, patch from outside of tires only, add air. Science folks

I set mine to door sticker and adjust for temperature swings.

I'm at 32psi cold and like the ride
23mpg every day, no reset since delivered

Have you tried Higher psi to notice any difference?

im at 37psi on front and 32 on back.. wondering if I am better off running lower on the front

Having dealt with side treadwear on other vehicles, I tend to keep mine 1-2 over the placard, to allow for those cooler days. - Still adjust seasonably, as 37 during the summer translates into 31-32 during the winter. (Every 10 degree change alters the pressure by 1 PSI).

Mine came from the dealer at 46 (dealer prep seems to have been a quick wash). Didn't notice till a week later. I had gotten used to the firm ride and 42 mpg.
I learned from reading on this site that 46 psi means the dealer didn't check the tires after delivery.
I now run them at 40.
Driving this truck makes me smile.

Why does Ford ship with higher psi than suggested on door placard?

Cause when you get your car/truck, more than likely the cold pressure they recommend (35) will be lower because of time?

To prevent flat spots from forming on the tires while sitting for potentially long periods. The dealer is supposed to deflate them to recommended pressure.

That makes sense, thanks
