The edges of the tire extend down over the laterally outer surface of the rim and the tire is secured to the rim by virtue of such extension. Various specific securing means may be employed on the tire. For example, the tire edges may be laced together under the rim, or inextensible beads in the tire edges may be actuated to grip the rim by the pneumatic pressure in the tire.
(1) Note. For tires embracing the rim and secured thereto by virtue of external clamps, see this Class, subclasses 397 and 398.
