Ford recommends 36psi. checked when cold all the way round. If you chose to run more or less that's up to you. As a large fleet shop manager/mechanic, its always been our companies policy to run what is on the door jam. We ignore what is on the tire as that's the max pressure for that tire and it can fit more that one specific vehicle.
I remember we had driver that had a heart attack and passed away at the wheel. He rolled his truck. The CHP impounded the truck and one of the first things they checked was the tire pressure, the second was the brakes, and then everything else. The tech that touched it last was very nerves. Fortunately all was OK for the tech, sadly not so much the driver.

I always run what Ford recommends on all my vehicles. Like I mentioned above, as the tires wear I adjust the psi accordingly.

Thanks guys

I'm gonna run them at the OEM spec 36psi as stated on the door sticker that (markboris) posted.
I've already noticed in only two days with them that the 19's have alot crisper, firmer, and more feel of the road versus the previous 17" tires. I couldn't imagine running 42psi.
My wife might complain about that ride. After-all it is her daily driver. LOL

I'll read the tires as they wear and adjust the air pressure accordingly.

Thanks

As stated on the vehicle for that rim and tire, 36 psi for front and rear. However I think it hugely depends on where and how you drive. If I ran 36 psi in my tires, the edges would wear out very quickly compared to the center. I live in a mountainous area and drive the car fairly hard sometimes. I run 45 psi and my tires are wearing very evenly and I have close to 30,000 miles on them. One note, I do not have the continental tires that came on the car. I am running Michelin Pilot Sport A/S 3's.

OK, "As stated on the vehicle" on the door jamb sticker is what I'm looking for.
So that states 36psi front and rear. Great!
Thanks guys!
