<p>A vehicle tyre with reduced rolling noise emission. The tyre tread is provided with one or more air-permeable channels or pores (6), which serve to neutralize air pressure differences between different parts of the tread surface in road contact, for example on each side of a tread block in a tread pattern. The invention also discloses how these channels or pores can be created by piecewise vulcanization of rubber or plastic balls, or otherwise shaped rubber or plastic bodies of which the tread is built up so that communicating channels or pores remain between such bodies. </p> |
