Tire pressure question ?

[The Lone Ranger]

Is it normal for there to be an 8# recommended tire pressure difference between the 255/65 R18 tires I have on my 2.3 Lariat (30#) and the 255/70 R17 tires I saw on a You Tube video for a 2.3 XLT (38#)? Mine does not have the Off Road Pkg - but a sticker I saw for a 2.3 Lariat with Off Road Pkg had same 30# number - so don't think it is the Off Road Pkg that makes a difference. Mine was delivered from dealer with pressures ranging from 34# to 38# on the four tires - so just trying to insure I have the right pressure.

Umm. The pressures Ford recommends are in s sticker inside the driver's door frame. Just use that or RTFM .

That's assuming you are using the tires that came with the truck. Tires will have the recommended pressure on the sidewall. My '21 with stock 265/60/18 says 35psi on the sticker.

Don’t use what’s on the tire that’s the maximum pressure use. What’s in the door jam

I just went thru the manual, I stand corrected.

They inflate them higher than normal for transport.

I have a 24 lariat fx4 with tow package and have had the same experience. It came from the dealer with 36# but the door sticker says 30#. I’ve tried both and found it didn’t seems to make difference except in fuel economy. Higher was better and the ride was the same.

I trust the tire manuf. More than ford. It's a suggestion. More air is generally better. Fuel and tire runs cooler but ride can be firmer, also more responsive in handling. I run 34 to 36#. Off roading in my jeep it's 18# but that's for traction and softer ride.

My 2.7 Lariat was delivered with tires at 40-41 PSI. I hate to say that I haven't aired them down to the rated pressure yet, lol.
