YSK how to find the proper air pressure for your tires - Lemmy.world

Every car is different and may require specific air pressure for your tires. This can be found on the frame of your driver’s door. This plaque will also tell you the recommended tires you should keep on your car per the manufacturer. This usually applies to your everyday driver that probably doesn’t have custom tires or rims that would null the recommended pressure for the car.

Also be aware many spare tires (those thinner ones you find in the car) have larger pressure
My Car has the same kinda tyre as a spare. Why would the spare tyre need to have larger pressure?
Yours wouldn't. The low profile, low weight ones do.
