What does it indicate when a wheel has developed "Chording"?

When a wheel has developed "Chording," it indicates that there is a flat spot on the wheel. This phenomenon occurs when the tread of the tire wears unevenly, often resulting from excessive heat, poor alignment, or improper inflation. As a result, the tire may lose its rounded profile, leading to a flat area that can affect the vehicle's handling and performance. Chording can also create a noticeable thumping or vibration while driving, as the tire's contact with the road becomes inconsistent. Recognizing this condition is vital for maintaining vehicle safety and handling characteristics, as it often requires immediate attention or tire replacement.
