How does tire pressure affect a vehicle's performance?

Tire pressure plays a crucial role in determining a vehicle's performance and overall driving experience. It influences various factors, including safety, handling, fuel efficiency, and tire lifespan.

When tire pressure is too low:

• Reduced safety: Underinflated tires increase the risk of tire failure, especially at higher speeds or during abrupt maneuvers. It may lead to blowouts or loss of control, compromising safety.
• Poor handling: Low tire pressure affects the vehicle's responsiveness and ability to corner and brake effectively. It can result in decreased traction and stability, making the car feel sluggish and less maneuverable.
• Increased rolling resistance: Underinflated tires create excess friction with the road surface. This increased drag causes the engine to work harder, resulting in reduced fuel efficiency and potentially higher fuel consumption.
• Uneven tire wear: Insufficient air pressure causes the tire's outer edges to excessively wear, while the center may remain relatively unaffected. This uneven wear pattern reduces the tire's lifespan and necessitates premature replacement.

On the other hand, when tire pressure is too high:

• Reduced comfort: Overinflated tires transmit more road imperfections and vibrations to the vehicle, leading to a harsher ride quality and discomfort for the occupants.
• Compromised traction: Excessive tire pressure reduces the contact patch between the tire and the road, resulting in decreased friction and traction. It negatively impacts braking performance, acceleration, and handling, particularly on wet surfaces.
• Uneven wear: Overinflated tires tend to wear out at the center, causing accelerated wear in that area. This uneven wear can impact the tire's lifespan and may require premature replacement.

To optimize a vehicle's performance, it is important to maintain the manufacturer-recommended tire pressure. Regularly checking and adjusting tire pressure not only ensures a safer ride but also improves handling, fuel efficiency, and the lifespan of the tires.
