Tire

Tire tread

A tire with a resonator for noise reduction includes: a main groove unit which has a plurality of main grooves formed to extend along a circumferential direction of the tire; a resonance unit which is formed between a pair of the main grooves; a neck unit which is provided to communicate the resonance unit with one of the pair of main grooves; and a cuff unit which is provided to connect the resonance unit and the other of the pair of main grooves.

Tires with resonators for noise reduction

Disclosed is a tire configured for reducing noise during running of the tire by forming a predetermined shape in a groove of the tire to reduce a peak of air column resonance sound. The tire with reduced noise includes a first protrusion formed on a sidewall of a groove, protruding in a depth direction of the groove, and dispersing sound waves generated in a tread, and a second protrusion formed on the sidewall of the groove, protruding in a longitudinal direction of the groove, and dispersing sound waves generated in the tread.

Tire with reduced noise

A pneumatic tire for a vehicle is herein disclosed. The pneumatic tire includes a tread, side walls, and beads. A plurality of tread blocks and grooves are formed in the tread. Kerfs are formed in the tread blocks. Each kerf face of each of the kerfs includes a flange portion, a plurality of concave kerf portions, and a plurality of convex kerf portions. The flange portion is formed in the outermost portion of the tread. The concave kerf and convex kerf portions are connected to the flange portion, and are alternately formed in depth and lengthwise directions of the kerf. The concave kerf portions correspond to opposite convex kerf portions. The convex kerf portions correspond to opposite concave kerf portions. The concave and convex kerf portions are configured such that the protrusion directions of the concave and convex kerf portions are opposite to each other.
