What effect does driving with worn-out tires have?

Driving with worn-out tires significantly reduces traction and increases stopping distances, which is crucial for safe driving. As tires wear down, the tread depth decreases, leading to diminished grip on the road surface. This is particularly noticeable in wet or slippery conditions where adequate tread is necessary to channel water away from the tire and maintain contact with the road.

Reduced traction can also affect cornering stability and overall vehicle handling, making it harder to control the vehicle during turns. Additionally, worn tires have a longer stopping distance; hence, if an emergency arises and immediate braking is required, the longer stopping time could result in an inability to avoid a collision.

The other choices provided do not accurately reflect the consequences of operating with worn tires. For instance, worn tires do not enhance fuel efficiency or improve handling capabilities, nor do they have no effect on vehicle performance. Instead, they compromise safety and handling, which emphasizes the importance of maintaining tires in good condition for optimal driving safety and performance.
