Alex :
Except... you're wrong... If you increase the tire size from 30 inches to 35 inches, you must use W = P * A (weight = internal pressure * contact area). This means the air pressure would go down in your specific example.

Why is my car losing tire pressure slowly in one tire it only has 20k miles

For Mercrdes-Benz, the correct tire pressure is listed in the gas tank door. The door jam is maximum load.

Okay, let me make sure I got this right. I take my door jam number (32 PSI) and add it to my tire number (52 PSI) and that’s the target number? I just put in 84 PSI and it doesn’t look right.

What if I put a F350 motor in my 1988 Honda Accord? Would that change the pressure?

BasketCaseCorey :
if I add a roll cage and a bigger engine say v4 to v6 adding to my total wight would I need to increase my tire pressure?

Had a flat once. We were dumb and when the donut said 60psi, we filled that sucker to 60psi. We got in the car and shut the doors. Or weight plus the vibration of the slamming door detonated the donut 😬

Would there be any point where you don’t follow the door jam? Just asking, seems like a good thing to know

If your car is too old and the sticker has worn out it’s super simple to Google the specs

piggy backing off this, why is it when im looking for tires the shop will ask for the make n model and the profile of the tire? what do the numbers mean and why are those important?

There are various benefits to going above or below the door jamb number- but never exceed tire rating

What if I dont have a door sticker?

Noah Mc Elroy :
but a wider tire has more contact area so shouldn't it run at a lower pressure to support the same weight?

Not sure the GM engineer planned for this in their pressure calcs...if there even was a sticker to follow 🤣
