How Often Do I Need To Look at Tire Pressure and Tread Depth?

You really should regularly inspect your vehicle's tire pressure because all tires will lose pressure as time passes, during both warm and cold temperature months. The weather isn't the only ingredient that results in a reduction in pressure either. Altitude shifts, flexing and tire wall impacts will slowly diminish air pressure. The most suitable procedure for optimal tire care is to check tire pressure almost every other visit to the gas station.

In terms of tread depth, you should check that every time you change your oil and you ought to rotate your tires every other oil change so that you can extend the life of your tires. Rotating your tires every 6 to 8 thousand miles can help sustain a level tread wear through the entire life span of the tire.

    What Are Ideal Tire Pressure and Tread Depth Levels?

    Ideal tire pressure levels will change by tire size and type. You'll find the optimal air pressure level listed in your vehicle owner’s manual or on the tire placard, which is usually mounted on your vehicle’s door edge, glove box or fuel door. Most tires may also have an ideal PSI range etched on the tire sidewall. As for tread depth, your tire is considered to be at the conclusion of its life once the tread is worn down to approximately 2/32 inches.
