How does tire pressure affect braking distance?

In terms of vehicle safety, tire pressure plays a crucial role in braking distance. Proper tire pressure is essential for efficient braking, as it directly affects the tire's contact patch and overall grip on the road.

When a tire is underinflated (low tire pressure), its contact patch increases, meaning more of the tire's surface area is in contact with the road. This might initially seem advantageous, but it leads to an uneven distribution of braking force. The extra flex in the underinflated tire causes it to have a larger rolling resistance, which diminishes traction and stability during braking.

Moreover, low tire pressure increases the likelihood of tire sidewall flexing, which can result in reduced braking response time. As a consequence, the braking distance is elongated, meaning it takes longer for the vehicle to come to a complete stop.

On the other hand, overinflated tires (high tire pressure) have a smaller contact patch. This reduces the grip between the tire and the road surface, leading to decreased braking efficiency. The lack of proper traction might result in longer braking distances and compromised safety.

To optimize braking distance, it is crucial to maintain the recommended tire pressure specified by the vehicle manufacturer. Regularly checking and adjusting tire pressure is a simple yet effective way to ensure better braking performance and enhance overall road safety.
