Asymmetrical tread is characterized by:

Asymmetrical tread patterns are designed with different tread designs on the inner and outer sections of the tire. This distinctive feature allows for better handling, traction, and stability because the inner part typically provides better grip, while the outer section is optimized for cornering performance. The markings that define the inside or outside wall serve as critical guidance for proper tire installation, ensuring that the asymmetrical design is oriented correctly for optimal performance.

In contrast, options suggesting a lack of markings or a completely symmetrical design misrepresent the characteristics of asymmetrical tread patterns. Additionally, a randomly designed surface would not provide the defined performance benefits that asymmetrical tread is intended to deliver. Thus, the correct characterization focuses on the specific markings that indicate the proper orientation and maximize the tire's intended functionality.
