ALWAYS check the tire! The door sticker can be generic and does not cover all tires. I run the MAX pressure (44) on my 20" as that is where you get the max weight rating (2450 I believe). Max also aids a bit in fuel mileage.
Always check your pressure when cold- like first thing in the morning after its sat for the night.

The door sticker is the recommended pressure for the exact stock tire the truck was equipped with.
The number on the tire is not the recommended pressure, but the max pressure, as you use anyway.

Bet that 78% is a free fill up too!Sorry - I'll elaborate - A lot of tire shops use a "nitrogen generator" - where they claim to be filling your tires with nitrogen. I know that it's an air dryer, so it only increases the % of nitrogen by removing other components (h2o) - which like you said - might bring it back to the 78% or so range. It's not the 100% nitrogen they want you to believe unless it comes directly from a tank. There are two "airs" that have good tire filling qualities - nitrogen & argon. Both are more temperature stable, and dont fluctuate the tire PSI between hot and cold temps as much as your normal air will.
I'm a little bitter on this - a couple years ago I took my old truck into a tire shop to get a tire patched. Dropped the tire off, put my card on file so I could just pick it up. Agreed on the normal $12 + tax for the patch, no big deal.
I come back the next day and my bill is over $20 including tax. I am
FURIOUS. Tax in my area is LOW, I was expecting $14 max. I start going over the charges out in my truck, and realize that they charged me for a nitrogen fill on the tire. I know better, know the benefits of nitrogen - and that they only have the generator so again - its only a concentration of it, not pure nitrogen like they'd want you to believe. Sooo I go back in and beotch to the manager. I tell him I NEVER asked for it, and I don't want it. That if I wanted nitrogen in my tires, it'd use the same cylendar of 100% nitrogen that we use for our race cars...not his fake ****."It's a standard charge, we fill all tires with nitrogen"
I didnt ask for it, I can fill it myself with nitrogen for free if I wanted - I only needed you guys to fill it with air to set the bead. You're not putting it on my truck, I'm just taking it home - you know/knew that.
"Well it's already in the tire, we have to charge you for it."
take it out! I dont want it, you can have it back...
"I'm sure you know that there isnt any way for us to take it out and get it back, we'd just be releasing it. Theres nothing to take back."
I never asked for it, never agreed to anything but the patch charge. You will be refunding my card the difference
"This credit card machine doesnt even have the capability to refund to a debit card. I'm sorry - theres nothing I can do"
Oh hell no, don't pull that on me - I have the same exact machine at my work. You can refund it as credit, and it will still go to my account. Now you're just lieing to me. (now i pull out the big guns) - I'm sure you know that I have done a lot of business through you guys, and my father's business does too - (they know my dad by name) - You're at risk to lose a lot of business over a charge that can easily be returned to me. It's your choice.
Guy ends up handing me $12 and some change in CASH.
....still havent taken any business back to them. Neither dad's company, nor myself. Thats normally 3-4 sets of tires per year between personal & business, and about the same # of patches per year.

Pretty sure Sean was talking about regular air.. I believe "air" is 78% nitrogen..
