What is an indicator that tires may need to be replaced?

Worn tread depth is a significant indicator that tires may need to be replaced. Tires are designed with specific tread patterns that provide traction and grip on the road. As the tread wears down over time, it becomes less effective in channeling water away from the tire, increasing the risk of hydroplaning and reducing overall vehicle control, especially in wet conditions. When the tread depth reaches a low level, typically around 2/32 of an inch, the tires are no longer safe for use, making it essential to replace them to maintain safety and performance.

In contrast, consistent air pressure is a sign of properly maintained tires, while regular balancing indicates that the tires are evenly worn and less prone to vibrations. A color change may reference cosmetic wear but does not directly correlate with the safety or functional effectiveness of the tire. Therefore, the assessment of tread depth is the most critical factor in determining tire replacement needs.
