Maintaining proper tire pressure is essential for several reasons closely related to vehicle performance and safety. When tire pressure is kept at the manufacturer’s recommended level, it ensures optimal traction because correctly inflated tires provide the right amount of contact with the road surface. This direct contact is crucial for effective braking, cornering, and overall handling of the vehicle, which contributes to safe driving.

Additionally, properly inflated tires can significantly improve fuel efficiency. Under-inflated tires can increase rolling resistance, forcing the engine to work harder and consume more fuel. Conversely, over-inflated tires can lead to a harsher ride and uneven wear patterns, potentially reducing the longevity of the tires and affecting performance.

In summary, maintaining proper tire pressure directly influences traction, fuel economy, and vehicle handling, making it imperative for both safety and efficiency on the road.
