Pneumatic tyres for a vehicle

摘要

The tire has a groove edge (2) found in a sectional level, which lies perpendicular to an extension of a groove laterally limited by the groove edge. The edge comprises edge surfaces with two axial radii (6, 7) that are adjoining together. The radius (6) adjoining at a groove bottom (3) forms a radial inner section of the groove edge. The radius (7) is assigned to the radius (6) under formation of an edge (8) extending parallel to the groove extension, and forms a radial upper section of the edge, where radius (7) is formed within an axial breadth (b2) and in a radial height (h2).
