摘要： 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.
