DEFINITION

Classification: 152/177

The tire secured detachable anti-skid armor with circumferential band is held to the tire by rings of smaller diameter than the tire tread, which rings are not secured to the wheel or tire but extend about the wheel at each side of the tread with the anti-skid armor attached thereto. The ring may be sectional but does not include any part of the armor. This subclass includes rings consisting entirely of chain.

(1) Note. For the securing means, see this class, subclasses 172, 179, 184, 189, 191, 225 and indented subclasses, and 242.
