Once again, I take my truck to the dealer for servicing and they lower the air pressure. With a Screw 4x4 plus a cap. I want the pressure on my P275 65-R18 at 40 pounds. The maximum is 44 pounds. 40 pounds is what it was at the dealer, they lowered it to 35lb. I wondered why my gas mileage sucked so bad. I often haul a trailer, with a bulldozer and have a lot of weight in the back.

The worst was when they only put 35 pounds in my Michelin Lt truck tires that recommended 45 pounds or more. When they lowered them to 35, my truck was swaying all over the road. They should at least ask what pressure I want them. I didn't tell them because all I wanted done was some alinement as my new truck pulled to the left. It wasn't tire pressure, I had that checked. I didn't think they would touch the tire pressure.

I imagine the dealer techs are trained to check everything when your in and adjust everything to factory specs. You'll just have to remember the next time you take it in to note to them what air pressure you want.

Your probably right, but I always seem to forget. But the recommended pressure on the door for a Screw 4x4 is totally wrong. Might be alright for a 2 door 2wd pickup but not the weight these trucks are.

I worked at a ford quick lane for almost a year and whenever they get a car in, no matter what its in for, they have to fill the air pressure. they always set it to 35 lbs unless its a van(e series) or superduty. They are told to put what it says on the sticker on the inside of your door. 90% of the trucks that come through still have stock tires and they're recommended for 35 lbs so that is whats put. 35 lbs is pretty standard for most ford cars/trucks unless like i said earlier its some type of commercial vehicle or heavy duty van/truck.

So if someone put's LT tires rated at say 80 psi max they'll still air them to 35 psi just because that's what on the door jamb. In case of a blowout due to their stupidity I wonder if they'll accept responsibility?

For an alignment, you always check air pressure first, and set it to specs, which is 35 for P tires.

The image of a f150 pulling a trailer with a bulldozer in it with flat tires made me laugh. Must be a real small bulldozer.

Most shops, ford or not, all do the same thing. Some even rotate them as a favor. I have another vehicle with aftermarket wheels and don't want the dealer to touch them, since I have my own specs and rotates I follow.. Just had it in for its second oil change, and on the service order, BIG BOLD letters, it states not to touch the tires.
And they follow my request.
Since a lot of guys have their own agenda, simply let them know next time you go in.

We will air the tires to factory specs. That is all. You want customs spec. That is your problem
