  • Patent number: 10155420
    Abstract: A vehicle tire (1), comprising a tread (2) which is intended for rolling contact against a surface, said tread (2) being formed with a tread pattern (20) which comprises circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the surface and the tire (1). The transverse groove (26) increases in width when progressing in a longitudinal direction of the transverse groove (26) from a sidewall (41, 42) of the tire (1) towards a center line (CL) of the tire and when progressing in a radial direction (R) outward from a base (263) of the transverse groove.

  • Patent number: 9764601
    Abstract: A vehicle tire (1), including a tread (2) which intended for rolling contact with a foundation, the tread 82) being formed with a tread pattern (20) which includes circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the foundation and the tire (1). The circumferential groove (25) has its wall (251) formed with a flow deflector (259) reducing a width of the circumferential groove (25), commencing from the wall (251) of the circumferential groove (25), bypassing a reduced-width portion (250) of the circumferential groove (25), and continuing arcuately into the transverse groove (26) so as to turn into a wall (261) of the transverse groove (26).
