Which of the following is NOT a tire mark characteristic?

• A. Brand
• B. Color
• C. Tread design
• D. Noise treatment

Answer: (B)

The key idea is what features of a tire actually imprint onto a surface in a way that can be used to compare a suspect tire to a known impression. The tread design is imprinted and preserves the geometric pattern of grooves, blocks, and transitions, so it serves as a concrete, matchable characteristic. The brand, while not a perfect fingerprint, can sometimes be inferred from distinctive tread patterns or manufacturing features that are reflected in the imprint. Noise treatment refers to design choices intended to reduce road noise, which can subtly influence the appearance of the tread in the mark and thus can be part of what an examiner notes when comparing impressions. Color, however, isn’t something that the imprint reliably conveys. The color of a tire mark depends on the rubber’s color, the surface it contacts, and lighting or coatings, not on a stable, identifying feature of the tire itself. So color isn’t a meaningful tire mark characteristic to compare for identification.
