Radial or bias ply tire for motorcycle or bicycle, comprising up to three layers of steel filaments at shoulder

摘要

The tire can be a bias ply tire with a central thread area (1), two side walls (2), bulbous beads (3) with inner cores (4), and two plies (5) wound in a diagonal pattern. The outer ends of the cords are guided around the core (4) and fixed. The thread (1) is designed as a crown (6) with lateral shoulders (7) with different gradients of curvature. A layer of steel filaments (8) is positioned between the thread (1) and the inner layer (5). The rolling friction is increased by using up to three layers of steel filament (8) in the shoulder area (7).
