What does everybody keep their tire pressure at?

[mrmike7189]

Oddly enough, my door sticker says 35 but Fordpass says "optimal cold tire pressure: 30"

Thats so strange because my door placard says 38 psi cold?

Here is mine. I have a 25 XLT FX4 2.7.

Look for this sticker. Mine 35

You may want to lower your pressure . It seems Ford ships all their vehicles with high tire pressure. Mine was 45 when it was delivered. Dealerships are supposed to lower pressure to recommended level as as part of new car prep but many overlook it.

Well I just looked and both of my stickers say 38psi. Build date of 11/24 with Goodyear Wrangler Territory AT's 255/70/17. Did Ford make a change at the end of the 2024 model year? 38psi cold means that when the tires are hot , they will be running at at least 40psi and higher.

Interesting. But I'm not surprised by Ford documentation.

I would suspect the different door stickers are related to differing trim levels and tire fitments.

I wonder why all the discrepancy? FX4 come with different Goodyear tires?

Ours came with 18" tires. 2025 Ranger FX4 4x4

Would agree as XLT has 17 and Lariat has 18

We were comparing identical tire models and sizes. Goodyear Wrangler Territory AT's 255/70/17. Both XLT. The only thing I can think of is that I have the V6 which may be heavier as my payload is lower. As the options go up, the payload becomes lower. I optioned my XLT with everything on the order list.

I think BriSco just figured it out. The V-6 engine vs. I-4 engine increased the curb weight.

But then I come in and state that my '25 Lariat FX4 2.7 badge states 30PSI....lol. Build date 4/25

 

[mrmike7189]

Ford recommends 30 for stock Lariat. 35 for the XLT and 38 for the XL.....am I correct? confused

A few things that can affect required tire pressure:

1: GVWR
2: Front/rear balance
3: Tow rating
4: Tire model
5: Tire aspect ratio
6: Intended use
7: Top speed
8: Suspension tuning
9: Tire size
10: Wheel width

I don't know all available models and options, but there are a number of possible specification combinations.

The list, however, goes on. That's why it's important to perform a chalk test and a shakedown after even seemingly innocuous modifications that involve wheels, tires and/or suspension.
