Vehicle tyre with a profiled tread

摘要

The tire has a profiled tread (1) that is sectioned by profile channels (2, 3) with a channel wall, which extends radially outwards from a channel base into profile positives (4). The channels limited to the profile positives are formed as a profile edge surface (5) that is bent radially outwards from a base contact surface. An angle included between the channel wall and a radial direction in a radial outer extension area of the wall is larger than in a radial inner extension area. The bending profile edge surface has large surface roughness than a surface of the base contact surface.
