Tread depth is important, but it’s only one part of the story.

1. Low tread depth remains the most obvious signal, especially when approaching legal limits.
2. Uneven wear patterns such as inner, outer or patchy wear often indicate alignment or balance issues and reduce overall performance.
3. Visible damage like cracks, cuts or bulges on the sidewall can compromise the tire structure and should never be ignored.

Tires often show signs through how the vehicle behaves.

4. Increased vibration, especially at higher speeds, can indicate imbalance or irregular wear.
5. Changes in road noise or comfort may signal that the tire is no longer rotating smoothly.
6. Reduced grip or stability, particularly in wet conditions or during braking, is a clear warning that performance is declining.

Even without visible wear, tires age.

7. Tire age is a critical factor. Rubber degrades over time, losing flexibility and grip. Most manufacturers recommend checking tires after 5 years, regardless of mileage. The production date can be found in the DOT code on the sidewall.

Recognizing these signs early helps maintain safety, stability and consistent performance on the road.
