Abstract: A plurality of traction devices are positioned transversely in spaced relation on a tire tread. Each traction device has a first end portion arranged to be guided into one of a plurality of troughs that are positioned on the periphery of a circular member mounted to the unexposed or inside rim of a vehicle wheel. The troughs are separated by crests to form a wave-like configuration on the periphery of the circular member. The first end portion is guided into a trough without the need to visually locate the point of attachment on the circular member. A portion of the first end portion is too large to pass through the trough and serves to secure the traction device to the inside circular member. A second end portion of the traction device is secured on the opposite side of the tire by connection to a second circular member or to the ends of the other traction devices to tightly position an antiskid body portion of the traction device on the tire tread.
