What is a sign of tire wear that requires immediate attention?

Uneven tread depth is a critical indicator of tire wear that requires immediate attention because it can significantly affect the vehicle's handling and safety. Tires are designed to have uniform contact with the road surface, ensuring optimal traction and stability. When the tread depth is uneven, it can lead to poor performance, increased stopping distances, and a higher risk of skidding or losing control, especially in wet or adverse conditions. Additionally, uneven wear might suggest underlying issues such as misalignment, improper inflation, or suspension problems that need to be addressed to prevent further tire damage and enhance safety.

Minor scuffs on the surface are generally cosmetic and do not typically compromise the tire's performance or safety. A change in color can indicate various conditions but does not necessarily relate to the structural integrity or operational capacity of the tire. Normal wear and tear is expected as tires age, but it does not always require immediate action unless specific indicators, like uneven tread depth, suggest a more urgent problem.
