6. A tire comprising:
a tread portion comprising a shoulder land region defined between a shoulder circumferential grove and a tread edge,
the shoulder land region circumferentially divided by shoulder lateral grooves into a plurality of shoulder blocks each having a block side wall and a block tread,
each of the shoulder lateral grooves comprising:
a first portion extending axially inwardly from the tread edge;
a second portion located on the shoulder circumferential groove side and inclined with respect to the first portion; and
a connect portion at which the first portion and the second portion are connected with each other, so that each of the shoulder blocks is provided with a convex corner portion which is convex toward the outside of the block at the connect portion
wherein
in the convex corner portion of each of the shoulder blocks,
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 on the outside in the tire radial direction, of a groove bottom of a respective one of the shoulder lateral grooves,
in the convex corner portion of each of the shoulder blocks, the third side wall extends to the tread edge,
the third side wall has a radially outer edge which is a boundary with the block tread of the each of the shoulder blocks, a first edge which is a boundary with the first side wall, a second edge which is a boundary with the second side wall, a connect point which is positioned at the tread edge, between the radially outer edge and the first edge, and another connect point between the first edge and the second edge,
a length of the radially outer edge along a longitudinal direction thereof is 25%or more and 45% or less of an axial width of the shoulder land region,
each of the shoulder blocks has an axial width smaller than a distance in the tire circumferential direction between the shoulder lateral grooves adjacent to each other in the tire circumferential direction, and
a distance in the tire axial direction from the another connect point to the tread edge is 4 mm or more and 6 mm or less.
