Abstract: A tire comprises a tread portion comprising a circumferentially arranged blocks divided by lateral grooves. Each block has a block side wall and a block tread. Each lateral groove comprises an axially outer first portion, an axially inner second portion, and a connect portion at which the first portion and the second portion are connected with each other so that each block is provided with a convex corner portion which is convex toward the outside of the block at the connect portion. In the convex corner portion, the block side wall comprises a first side wall extending along the first portion, a second side wall extending along the second portion, and a substantially triangular third side wall intersecting the first side wall, the second side wall and the block tread. The third side wall terminates radially outside the groove bottom of the lateral groove.

Abstract: A tire includes a tread portion provided with a first land region demarcated between a shoulder circumferential groove and a tread edge. The first land region is provided with first sipes extending in a tire circumferential direction, axial sipes, and first axial grooves extending from the tread edge. The first sipes are not connected with the first axial grooves. Each of the axial sipes has an axially inner end connected with the shoulder circumferential groove. Each of the axial sipes has an axially outer end connected with one of the first sipes.
