What may indicate that a tire needs a replacement?

A tire needing replacement can often be indicated by visible cracks or bulges on the sidewalls. These physical deformities can suggest that the tire’s structural integrity has been compromised, potentially leading to failure during use. Cracks may arise from prolonged exposure to sunlight or harsh weather conditions, while bulges usually suggest internal damage, such as a broken belt or impact injury. Both conditions mean the tire can no longer perform safely and reliably, necessitating replacement for the driver’s safety.

In contrast, even tread wear across the surface is typically a sign of proper alignment and balanced tires, indicating that the tire is still usable. All-weather capability describes a tire’s performance characteristics rather than its condition. Lastly, a smooth surface texture can simply result from normal wear, and unless it is excessively worn down, it may not indicate the immediate need for replacement. Therefore, the presence of visible cracks or bulges is a clear, actionable sign that a tire must be replaced for safe operation.
