Provided is a tire capable of efficiently discharging water, which is additionally absorbed through a plurality of flow tubes, through the flow tubes and a drain tube, thereby improving wet grip performance. The tire with enhanced wet grip includes a kerf formed on a block to discharge water introduced thereinto to a groove, a drain tube formed in the kerf in its longitudinal direction and connected to the groove to discharge the water to the groove, and a flow tube formed in the kerf toward the drain tube from an inlet of the kerf, into which the water is introduced, and connected to the groove or the drain tube.

Tire with enhanced wet grip

A tire includes a reinforcing rib formed on a groove to prevent irregular wear of a tread and including an auxiliary hidden groove formed in the groove to enhance capabilities of water absorption and drainage of the tire even when the reinforcing rib is formed on the groove. The tire can include a reinforcing rib coupled to a first sidewall, which is one of both sidewalls forming the groove, and protruding toward the groove from the first sidewall, a hidden groove formed in one portion of a second sidewall which is the other of the sidewalls forming the groove, and a remaining tread part protruding toward the groove from a side surface of the hidden groove, the remaining tread part being the other portion of the second sidewall.

Tire for preventing irregular tread wear

A tire having includes a V-shaped kerf to increase the directionality of running of the tire and having a drainage section at the lower side of the kerf to enhance (e.g., improve) the water drainage performance. The tire having V-shaped kerfs includes a kerf formed on a block and allowing water introduced thereinto to be discharged to a groove, and a drainage section connected to the groove to discharge the water to the groove, the drainage section being a space defined in the longitudinal direction of the kerf.
