We cannot read your mind. Tell the service advisor that you would like them at xx psi it's that simple

I went to Discount tire (a great outfit) and they mistakenly aired my tires to about 35psi. Even the printed work order said "55 front, 60 back.
I'll have a talk to them next time.

Yeah maybe! That could happen, but also if someone has those types of tires they take it in for "the works" then they should definitely let the shop manager know that they require 80 lbs.

If you are running your tires at whatever is listed at the max PSI on the sidewall then you have way too much air pressure in your tires.

If the weight of your vehicle actually requires so much weight capacity out of each of your tires that you actually have to run them at max PSI you need a higher load range tire.

It is a smaller bulldozer, but not that small. You don't even know it is back there.

It's nice to actually see service techs doing their jobs. Way too many times I've had service done and simple things are ignored. Airbox left open, fluids not filled etc. Once I had only two tires swapped when I had paid for a rotation.

Sounds to me like your shop pays attention to detail. I'm sure if you state you have XX pressure and want that maintained they will oblige.

I set my tires at 40 psi... so when the dealer is all proud to say "we checked everything today, including tire pressure", I assume they set it back to 35...
so, I get the compressor out when I get home (after they cool down), ready to air these puppies back up, and lo and behold... they're still at 40... so that tells me that my dealer is not as detail-oriented as yours, or in other words, they just do the bare minimum (I hope) and don't give a flying f**k about any non-essential maintenance items...
so yeah, just tell them what you want, but at any rate I dont think 35psi is gonna cause any "damage" to your tires or truck.

Imagine if you will that they knowingly let you drive your vehicle away from their shop with your tires inflated higher than specified by Ford, and you have a blowout and someone dies as a result. The three remaining tires are all over inflated and come to find out the dealership over inflated the tires...who wins that lawsuit?

Feathermerchant

It probably doesn't matter but I do not think I have ever heard of a blowout due to overinflated tires.

To me the issue is this:
The Govt thinks it would be a good idea to put a sticker on every car with (Mfr) recommended tire pressures. Great for the first set of tires. Tires wear out. When they are replaced, they may or may not have the same load/pressure rating. So even though the techs at the tire store/dealer think (and are trained) that they should inflate to the sticker, that may not be the correct tire pressure.

It is not just trucks. I replaced 2 of the tires on my wife's minivan with two new tires of the same size and model and Mfr. The old tires had a max inflation of 44psi. The new were 51psi. I showed this to the tire store tech. He said just to inflate to the sticker. But he couldn't explain why.

Truck example: You replace your P-metric tires with a max inflation pressure of 35psi with load range C 50psi tires. Should you stick to the sticker pressure?
What if you go to a larger tire or tire/wheel?

I just think the sticker is too dumb for the real world.

Before the Ford Explorer/Firestone tire issue, Ford recommended lowering the tire pressure instead of changing the tire spec. Ford is VERY sensitive to tire pressure. The dealers do it for liability purposes.
