Abstract
A tyre comprises a tread portion having a land region including a ground contacting surface defined between a first vertical edge and a second vertical edge and a lateral groove including a first portion extending from the first vertical edge, a second portion extending from the second vertical edge, and a connection portion connecting therebetween. The connection portion is a portion between a first small edge protruding circumferentially from the first portion and a second small edge protruding toward a circumferentially opposite side to the first small edge. A length in the tyre circumferential direction of each of the first and second small edges is smaller than a maximum groove width of each of the first and second portions. At least a part of the connection portion has a raised bottom portion having a depth smaller than that of the lateral groove at the first and second vertical edges.
