What can be a consequence of driving with worn tires?

Driving with worn tires significantly impacts vehicle safety and performance, particularly in wet conditions. When tires lose their tread, their ability to channel water away from the contact surface diminishes. This leads to a higher risk of hydroplaning, where the tires lose contact with the road due to a layer of water, making it difficult for the driver to control the vehicle.

In contrast, improved fuel economy, a smoother ride, and increased engine efficiency are typically linked to tires that are in good condition. Worn tires can degrade fuel efficiency because they create more rolling resistance. A smoother ride would also be compromised as worn tires often lead to a harsher driving experience due to decreased shock absorption. Therefore, the correct answer highlights a significant safety issue that arises from neglected tire maintenance.
