Tire pressure goes down when the temperature fluctuates, which leaves your tires over- or under-inflated. This causes excessive wear on your tire’s tread, reduces traction for your car, and uses more gas. We recommend checking your car tire’s air pressure (measured in “pounds per square inch” or “psi”) every month, especially in winter.
You can find the right tire pressure (psi) for your car in the driver-side door jamb, on a sticker in your glove compartment, or in the owner’s manual. To find out when it’s time to change your tires, check your tire tread regularly.
