Tire

摘要

In a tread part (1), a tilted land portion (200) is divided into multiple blocks by a tilted narrow groove (300) and branched narrow grooves (350). Tilted main grooves (100) include an upper tilted main groove (101) and a lower tilted main groove (102). The branched narrow grooves (350) include first branched narrow grooves (350a) and second branched narrow grooves (350b). First blocks (210) and second blocks (220) have quadrilateral or pentagonal shapes. Of the first blocks (210), one first block and another first block adjacent to the one first block in a tilt direction KC have the same shape. Of the second blocks (220), one second block and another second block adjacent to the one second block in the tilt direction KC have the same shape.
