the latest production model.
6.2 Tread Design—The upper surface of tread shall have
one or a combination of the following:
Class 1 Smooth (Flat)
Class 2 Pattern: Embossed, Grooved, or Ribbed
Group 1 Abrasive Strips: Embedded
Group 2 Contrasting Color for Visually Impaired
6.2.1 Class 1, Smooth (Flat)—The tread surface shall be
smooth and flat.
6.2.2 Class 2, Pattern: Embossed, Grooved, or Ribbed—
