Final answer:
Underinflated and overinflated tires negatively impact traction by reducing the contact patch with the road, while properly inflated tires provide optimal traction.
Step-by-step explanation:
When it comes to tire traction, the inflation level plays a crucial role. Underinflated tires have reduced traction because the tire's contact patch with the road is smaller, resulting in less grip. This can lead to decreased control over the vehicle and an increased risk of accidents, especially in wet or icy conditions.
On the other hand, overinflated tires also affect traction negatively. An overinflated tire has a smaller contact patch, which reduces the amount of grip on the road. This can cause the tires to slide or skid easily, especially when making turns or sudden stops.
Properly inflated tires, with the recommended tire pressure specified by the manufacturer, provide optimal traction. The tire's contact patch is maximized, allowing for better grip and control on the road surface. This is crucial for safe driving, especially in challenging conditions.
