ABSTRACT:
An annular meshwork to cover the tread and part of the sidewalls of a tire includes a plurality of flexible, nonstretchable strands extending around the tire, each strand being connected to adjacent strands at spaced apart points to form an annular meshwork or network to improve traction and steering. The sides of the meshwork are defined by end rings, at least one of which is extensible, e.g., elastic, to allow mounting on the tire. The strands adjacent the end rings are fixedly attached to the end rings. The meshes are formed by the strands with a significantly longer dimension in the circular direction of the annular meshwork than in the transverse direction. The connections can be made using clamping devices of which specific embodiments are disclosed. The clamping devices can be provided with a protective layer on the tread-facing (inner) side. The outer side can be provided with projections in the nature of short spikes to enhance traction. The inner end ring can be made using a steel strip bent into a ring and surrounded by a spiral ring, the ends of the strip being overlapping and provided with a locking clamp to reduce the ring diameter after installation on a tire.
