Why is tread depth measurement important?

Measuring tread depth is crucial because it directly affects a vehicle's grip and safety on various road surfaces. Adequate tread depth helps improve traction, especially in adverse weather conditions like rain, snow, or ice. Tires with proper tread depth can channel water away from the contact area between the tire and the road, reducing the risk of hydroplaning and improving vehicle handling and stopping distances.

Furthermore, insufficient tread depth can lead to decreased performance, making it harder to control the vehicle. This can result in longer stopping distances and an increased risk of skidding. Therefore, maintaining the correct tread depth is vital for ensuring overall road safety and effective tire performance, making this choice the most relevant and important reason why tread depth measurement is necessary.
