What is a common sign that may indicate tires need inspection?

A common sign that may indicate tires need inspection is unusual tread depth across the tire surface. This irregularity can suggest uneven wear patterns, which might stem from issues such as improper inflation, misalignment, or suspension problems. The tread depth is critical for ensuring that tires grip the road effectively, especially in wet conditions. If one part of the tire tread is significantly more worn than another, it may impact vehicle handling and safety.

While tire rotation is a necessary maintenance practice to ensure even wear on all tires, it is not an indication of an issue but rather a preventative measure. The presence of a sheen on the tires can suggest certain conditions like exposure to oils or chemicals but does not directly indicate tread wear or the need for inspection. Similarly, while all tires feeling warm after driving might indicate normal operation, it does not specifically point to the need for tread inspection or reveal potential issues with tire condition.
