TYRE

A tyre includes a tread portion including a row of blocks arranged in a tyre circumferential direction divided by lateral grooves (4); each block (5) includes a block tread surface, a first block sidewall surface (7) located on a leading side in a rotation direction of the block, and a leading-side corner portion (10) between the block tread surface and the first block sidewall surface; the leading-side corner portion (10) includes a first portion (11) and a second portion (12) extending in a tyre axial direction; the first portion (11) is formed sharper than the second portion (12); in a plan view of each block, an angle θ1 of the first portion (11) to the tyre circumferential direction is larger than an angle θ2 of the second portion (12) to the tyre circumferential direction; each lateral groove has a groove width (A) at the first portion (11) that is larger than a groove width (B) at the second portion (12).
