What does PSI stand for in tire maintenance?

PSI stands for "Pounds per square inch" in tire maintenance. This measurement is crucial because it indicates the pressure of air within a tire, which directly affects vehicle performance, safety, and fuel efficiency. Maintaining the correct PSI helps ensure optimal tire wear, handling characteristics, and reduces the risk of tire blowouts.

Tire manufacturers provide recommended PSI levels, which can usually be found on a sticker inside the driver's door or in the owner's manual. Regularly checking and maintaining the correct PSI is an important part of vehicle maintenance that contributes to overall driving safety and efficiency.
