What is the effect of low tire pressure on vehicle performance?

Low tire pressure significantly affects vehicle performance primarily by reducing traction and increasing tire wear. When a tire is under-inflated, it has a larger contact patch with the road. This can lead to less efficient handling because the tire can flex and deform excessively. This deformation reduces the tire's ability to grip the road surface, impacting acceleration, braking, and cornering, ultimately leading to compromised safety.

Additionally, low tire pressure causes the tire to heat up more quickly due to increased rolling resistance. The excessive heat can lead to premature tire wear, shortening the tire's lifespan. The sidewalls of the tire may flex more than intended, leading to structural damage over time. Maintaining the correct tire pressure is essential for optimal performance, ensuring the vehicle handles correctly, consumes fuel efficiently, and supports the longevity of the tires.
