Tire

A tire comprising:

• a tread with a groove, the groove having a snow trapping device attached to a bottom wall and to opposing side walls of the groove, the snow trapping device having:
• a planar first surface facing a first side in a groove longitudinal direction, the first surface extending at right angles with respect to each of the bottom wall and the opposing side walls;
• and
• a planar second surface facing a second side opposite the first side in the groove longitudinal direction, the second surface being inclined from the bottom wall to an apex of the first surface,
• wherein parts of the snow trapping device overlap along the groove longitudinal direction to form a passageway for water through the device in the groove longitudinal direction,
• wherein the passageway comprises a sipe and a hole extending through the first surface and the second surface in the snow trapping device, the sipe being formed outside the hole in a tire radial direction and adjoining the hole,
• wherein when the snow trapping device passes through a contact patch of the tire, the parts which overlap are joined to, or in contact with, each other wherein the passageway is formed between a joining point or a contact point and the bottom wall and the sipe is provided at the contact point which allows the parts to contact each other,
• wherein the height of the snow trapping device is less than the depth of the groove.
