  "textContent": "The present invention provides a tire for a two-wheeled vehicle which allows for maintaining traction performance and braking performance at a high level, by reducing the adhesion of mud to groove bottom surfaces in the center portion of a tread. Provided is a tire for a two-wheeled vehicle including a tread portion (10) formed in an annular shape. In the tire for a two-wheeled vehicle, a plurality of blocks are formed in the tread portion. When the tread portion is divided in the tire width direction into three portions of a tread center portion (10C) including the tire equator and a pair of tread shoulder portions (10S) including tread edges, a plurality of protrusions (21) are provided on groove bottom surfaces in the tread center portion, and each of the protrusions has an aspect ratio H/D of 0.2 or more and 1.0 or less. The aspect ratio H/D of each protrusion is defined by the maximum width D of a plane at which the protrusion is in contact with the groove bottom surface and the height H of the protrusion relative to the groove bottom surface.",
