Abstract
A tyre includes a tread portion including first and second land portions. The first middle land portion is provided with first middle lateral grooves traversing the first middle land portion completely. The second middle land portion is provided with second middle lateral grooves traversing the second middle land portion completely. Each of the first middle lateral grooves and the second middle lateral grooves is a curved groove which includes a first convex portion located on a first side with respect to a groove-reference-straight-line that connects both ends of a groove centerline of the curved groove and a second convex portion located on a second side with respect to the groove-reference-straight-line, and a circumferential length of the groove-reference-straight-line of each first middle lateral groove is smaller than a circumferential length of the groove-reference-straight-line of each second middle lateral groove.
