What does it mean if a driver sees "bald" tires on another vehicle?

Seeing "bald" tires on another vehicle indicates that the tires have minimal or no tread remaining, which significantly affects traction and safety. The term "bald" refers to the wear of the tire tread, and when tires are bald, the wear indicators or wear bars become visible, suggesting that the tires are not safe for driving. This is crucial as tires that lack sufficient tread can lead to reduced handling ability, increased stopping distances, and a higher risk of hydroplaning in wet conditions. Therefore, the correct interpretation of seeing bald tires is that they are unsafe due to the presence of these wear bars, which serve as indicators that the tire has reached the end of its useful life and should be replaced.
