A tyre comprising: a tread portion comprising a tyre equator, a tread edge (Te), a tread width which is a distance in a tyre axial direction from the tyre equator to the tread edge (Te), the tread edge (Te) being the axial outermost edge of the ground contacting patch of the tyre which occurs under a normal loaded condition such that the tyre under a normal state is grounded on a plane with a standard tyre load at zero camber angles, and a shoulder land portion comprising the tread edge (Te), the shoulder land portion being provided with a plurality of first shoulder lateral grooves, each first shoulder lateral groove comprising an inner groove portion extending inwardly in the tyre axial direction of the tread edge (Te) and an outer groove portion extending outwardly in the tyre axial direction of the tread edge (Te), wherein each first shoulder lateral groove, in a tread development view, has a groove area (Sb) of the outer groove portion extending in a region from the tread edge (Te) to an 125% position of the tread width is greater than a groove area (Sa) of the inner groove portion, and in each first shoulder lateral groove, the outer groove portion comprises an inner position, an outer position located outwardly in the tyre axial direction from the inner position by 5% to 20% of the tread width, and an intermediate position located at a center between the inner position and the outer position in the tyre axial direction, characterized in that a ratio (Hb / Ha) of a groove width (Hb) in a tyre circumferential direction of the intermediate position to a groove width (Ha) in the tyre circumferential direction of the inner position is smaller than a ratio (Hc / Hb) of a groove width (Hc) in the tyre circumferential direction of the outer position to the groove width (Hb). a tread portion comprising a tyre equator, a tread edge (Te), a tread width which is a distance in a tyre axial direction from the tyre equator to the tread edge (Te), the tread edge (Te) being the axial outermost edge of the ground contacting patch of the tyre which occurs under a normal loaded condition such that the tyre under a normal state is grounded on a plane with a standard tyre load at zero camber angles, and a shoulder land portion comprising the tread edge (Te), the shoulder land portion being provided with a plurality of first shoulder lateral grooves, each first shoulder lateral groove comprising an inner groove portion extending inwardly in the tyre axial direction of the tread edge (Te) and an outer groove portion extending outwardly in the tyre axial direction of the tread edge (Te), wherein each first shoulder lateral groove, in a tread development view, has a groove area (Sb) of the outer groove portion extending in a region from the tread edge (Te) to an 125% position of the tread width is greater than a groove area (Sa) of the inner groove portion, and in each first shoulder lateral groove, the outer groove portion comprises an inner position, an outer position located outwardly in the tyre axial direction from the inner position by 5% to 20% of the tread width, and an intermediate position located at a center between the inner position and the outer position in the tyre axial direction, characterized in that a ratio (Hb / Ha) of a groove width (Hb) in a tyre circumferential direction of the intermediate position to a groove width (Ha) in the tyre circumferential direction of the inner position is smaller than a ratio (Hc / Hb) of a groove width (Hc) in the tyre circumferential direction of the outer position to the groove width (Hb).
