You use a tire gauge to check your car's tires. Where do you find the correct pressure (psi) for them?
Correct answer: The owner's manual or the driver's side door jamb
Why
Check tire pressure with a gauge and compare it with the recommended psi in the owner's manual or on the driver's side door jamb. If the pressure is too high, let air out; if it is too low, add air until it matches. Correct pressure helps the tires grip, brake and wear evenly. Also check the tires for wear and damage once a month and before a long trip.
