What is the main reason for maintaining proper tire pressure?

Maintaining proper tire pressure is crucial primarily because it directly impacts traction and control. When tires are inflated to the appropriate pressure, the contact surface between the tire and the road is maximized, allowing for better grip and handling. This enhances the vehicle's performance in various driving conditions, improving stability during cornering and braking. Proper tire pressure also ensures that the tires wear evenly, extending their lifespan and maintaining optimal performance.

Additionally, when tire pressure is too low or too high, it can lead to decreased fuel efficiency, increased wear, and a higher risk of tire blowouts, all of which can jeopardize safety and lead to more significant vehicle issues. Therefore, keeping tires at the manufacturer's specified pressure is key to maintaining vehicle safety and performance.
