In tire tread analysis, which features are considered individual characteristics?

• A. Wear patterns, cuts, and nicks unique to one tire
• B. Brand and model of the tire
• C. Tire color
• D. Inflation pressure

Answer: (B)

In tire tread analysis, what makes a feature useful for individual identification is its unique, random nature that comes from a specific tire’s history. Wear patterns, cuts, and nicks develop from use, damage, and manufacturing quirks in a way that is not shared by every tire. These distinctive markings can, in principle, link a tire to a particular source because they are idiosyncratic to that tire rather than to a broad category.

Brand and model, on the other hand, describe the tire’s type and design and thus are class characteristics rather than unique to one tire. Tire color and inflation pressure aren’t reliable indicators of a single tire’s identity either, since color can vary with appearance and cleaning, and inflation pressure can change with time and conditions.

So, the features considered individual characteristics are the wear patterns, cuts, and nicks that are unique to one tire.
