The tire (1000) includes: a groove portion (100, 200, 300, 400) which is formed to extend circumferentially along a circumference of a tire tread; and a knurled portion (120, 220, 320, 420) which is formed on bottom and side surfaces of the groove portion. The knurled portion (120, 220, 320, 420) is provided to reduce noise energy by narrowing an air path formed when the groove portion (100, 200, 300, 400) and the ground contact each other.",
