Why are bald tires considered unsafe?

Bald tires are considered unsafe primarily because they can cause hydroplaning. When a tire is bald, its tread has worn down significantly, which leads to a reduced ability to channel water away from the tire's surface. On wet roads, this can result in the tire losing contact with the road as it skims over the water, making it difficult for the vehicle to maintain control. The risk of hydroplaning increases significantly, especially at higher speeds, leading to dangerous driving conditions.

The other aspects regarding tire performance do not hold true with bald tires. While some may mistakenly think bald tires enhance fuel efficiency, they actually can lead to more fuel consumption due to decreased traction. Similarly, bald tires typically increase stopping distance rather than decrease it, which compromises braking effectiveness. Lastly, they do not offer better traction on wet roads; rather, worn-out tires struggle to grip the road, further heightening safety risks. Thus, the correct understanding of bald tires is crucial for maintaining vehicle safety.
