A motorcycle tire comprising: a tread portion having a designated rotational direction and an arc-shape outer surface protruding radially outwardly; the tread portion being provided with a circumferentially and continuously extending central main groove in a zigzag shape, a plurality of first lateral grooves arranged on both sides of the central main groove, a plurality of second lateral grooves arranged on both sides of the central main groove, and a plurality of shoulder grooves arranged on both sides of the central main groove; the central main groove comprising a plurality of first inclined elements across a tire equator having a first angle (θ1) with respect to a circumferential direction of the tire, a plurality of second inclined elements across the tire equator having a second angle (θ2) with respect to the circumferential direction of the tire in an opposite direction to the first inclined elements, and a plurality corners each between one of the first inclined elements and one of the second inclined elements, each corner being located within a crown region (Ce) that comes into contact with a ground when the tire is mounted on a standard rim with a standard pressure and is loaded with a standard tire load at a camber angle of zero; each first lateral groove extending axially outwardly toward the rotational direction from one of the corners of the central main groove, the first lateral groove having a third angle (θ3) with respect to the circumferential direction of the tire, the third angle (θ3) being greater than or equal to the first and second angles (θ1, θ2); each second lateral groove extending axially outwardly toward the rotational direction from one of the first inclined elements or one of the second inclined elements, the second lateral groove being inclined in an opposite direction with respect to the first or second inclined element to which the second lateral groove is connected; and each shoulder groove being disposed outside the crown region (Ce) and connected to one of the second lateral grooves; wherein one of the shoulder grooves is inclined axially inwardly toward the rotational direction at an angle (θ5) of not more than 40 degrees with respect to the circumferential direction of the tire. a tread portion having a designated rotational direction and an arc-shape outer surface protruding radially outwardly; the tread portion being provided with a circumferentially and continuously extending central main groove in a zigzag shape, a plurality of first lateral grooves arranged on both sides of the central main groove, a plurality of second lateral grooves arranged on both sides of the central main groove, and a plurality of shoulder grooves arranged on both sides of the central main groove; the central main groove comprising a plurality of first inclined elements across a tire equator having a first angle (θ1) with respect to a circumferential direction of the tire, a plurality of second inclined elements across the tire equator having a second angle (θ2) with respect to the circumferential direction of the tire in an opposite direction to the first inclined elements, and a plurality corners each between one of the first inclined elements and one of the second inclined elements, each corner being located within a crown region (Ce) that comes into contact with a ground when the tire is mounted on a standard rim with a standard pressure and is loaded with a standard tire load at a camber angle of zero; each first lateral groove extending axially outwardly toward the rotational direction from one of the corners of the central main groove, the first lateral groove having a third angle (θ3) with respect to the circumferential direction of the tire, the third angle (θ3) being greater than or equal to the first and second angles (θ1, θ2); each second lateral groove extending axially outwardly toward the rotational direction from one of the first inclined elements or one of the second inclined elements, the second lateral groove being inclined in an opposite direction with respect to the first or second inclined element to which the second lateral groove is connected; and each shoulder groove being disposed outside the crown region (Ce) and connected to one of the second lateral grooves; wherein one of the shoulder grooves is inclined axially inwardly toward the rotational direction at an angle (θ5) of not more than 40 degrees with respect to the circumferential direction of the tire.
