kobowden93, thanks for asking the question!
I’m a guy … safe to say (based on your photo) that I’ve been driving L-O-N-G before you were born
I DIDN’T KNOW that I should always use the tire pressure from the door jamb sticker. Probably the majority of the time I’ve checked air/tire pressure I went by the information on the tire. Maybe once in awhile I used info from the owner’s manual … so, thanks to you I now know something I didn’t before you asked your question! ; ) (of course, the explanation makes perfect sense – but 'ya don’t know what 'ya don’t know.)
I confess I don’t check tire pressure as often as one ‘ought to’ – once-a-week seems (to me) to really be on the high-side … but I don’t dispute any knowledgeable person who gives that advice. I did buy, btw, a dial-type tire pressure gauge that screws onto the tire valve. I found it WAYYY easier to use and accurately read, then the less expensive “push and slide” gauges. As they say, “back-in-the-day” gauges connected to air hoses at gas stations were generally considered to be inaccurate – as were the air-hose dispensers where you dial the pressure you want. A couple of comments in this tread ; ) intimated that those gauges may be more accurate now.
As an homage to Click & Clack I leave you with this chuckle ; ) I used to live in Colorado (Denver elevation 5,280 feet – the “mile-high city”). When friends/acquaintances would move to Colorado, it would not be ‘unusual’ for someone to ask if they had their carburetor adjusted, and the air changed in their tires. They usually had done the carburetor adjustment, but (of course) would ask “whadda mean, change the air in the tires?” With a straight face one would simply explain that they had low-altitude air in their tires, and because of the atmospheric difference at this much higher altitude, the old air needed to be removed and replaced … adding “any gas station will gladly do that for you”.
And off they would go – to make some mechanic’s day! ; )
–of course I would never do such a thing – but some would.
