What indicates that a tire may need to be replaced?

The presence of visible damage, bulges, and tread depth below the legal limit clearly indicates that a tire may need to be replaced. Visible damage, such as cuts or bulges, compromises the structural integrity of the tire, making it unsafe for driving. Additionally, tread depth is crucial for maintaining traction, especially in adverse weather conditions. If the tread is below the legal limit, it indicates that the tire is worn out and unable to grip the road effectively, which can lead to decreased handling and increased risk of skidding or hydroplaning.

Uniform wear across the surface suggests that the tire is wearing evenly and may still be in good condition, while low air pressure alone can often be rectified without requiring replacement, and normal winter wear does not necessarily indicate that a tire is at the end of its lifespan.
