What do "tread wear indicators" refer to on tires?

• A. Indicators that show tire pressure
• B. Raised sections in the tire tread that show when tires are worn out
• C. A type of gauge for tire alignment
• D. Markers for seasonal tire changes

Answer: (B)

Tread wear indicators, also known as wear bars, are specifically designed features on tires that indicate when the tread has worn down to a level where the tire needs to be replaced. These raised sections are strategically molded into the tire’s tread pattern at various points. As the tire wears down, the tread depth decreases, and once the tread wears down to the level of these indicators, it signals that the tire has reached a critical level of wear. At this point, the tire's traction capabilities are significantly reduced, which can compromise safety due to decreased handling performance, especially in wet or slippery conditions. Recognizing these indicators allows drivers to make informed decisions about tire replacement, ensuring both safety and optimal performance on the road.
