What does the traction rating of a tire measure?

The traction rating of a tire specifically measures the tire's ability to stop on a wet surface, which is crucial for ensuring safety during wet driving conditions. This rating informs drivers about how well a tire can grip the road when it is slippery, helping to prevent hydroplaning and improve overall vehicle stability. A higher traction rating indicates better performance in wet conditions, which directly influences stopping distances and the vehicle’s ability to maintain control in adverse weather.

Understanding traction ratings is essential for making informed decisions about tire selection, particularly in regions that experience significant rainfall or wet weather conditions. This information helps ensure that drivers have the necessary grip to stop effectively and navigate safely. The other options relate to different aspects of tire performance but do not pertain specifically to the traction rating, making them less relevant in this context.
