Tire

A tire, comprising:

• a carcass made of at least one carcass layer;
• and
• a belt comprising a first belt layer and a second belt layer disposed on an outer side of the first belt layer in a radial direction, the first belt layer comprising a cord extending from an inner side toward an outer side in a tire width direction on one side in a tire circumferential direction, the second belt layer comprising a cord extending from the inner side toward the outer side in the tire width direction on another side in the tire circumferential direction;
• when, in a tire see-through plan view, an inclination angle of the cord included in the second belt layer with respect to the tire width direction is defined as a positive inclination angle,
• in a tire meridian cross-sectional view, an intersection point between a perpendicular line drawn from an end portion of a belt layer having a maximum belt width in the tire width direction to the carcass and a cord of an outermost carcass layer in a tire radial direction is defined as a first reference point, and
• in the tire see-through plan view, an inclination angle of the cord of the outermost carcass layer with respect to the tire width direction at the first reference point being more than 0° on each side in the tire width direction;
• wherein when, in the tire meridian cross-sectional view, a dimension along a tire profile from a tire equatorial plane to a tread surface position identical to a position of the first reference point in the tire width direction is defined as Tr, a point on an inner side by 0.1 Tr in the tire width direction from the first reference point along a profile of the carcass is defined as a second reference point, and a center region is defined between the second reference point on each side of the tire, the inclination angle of the cord of the outermost carcass layer is constant and parallel to the tire width direction across a majority of the center region including at the tire equatorial plane;
• the belt layer having the maximum belt width in the tire width direction extends continuously between the first reference point on each side of the tire;
• a groove is formed in a region in the tire width direction from a position on an inner side by 0.3 Tr in the tire width direction from the tread surface position along the tire profile to a position on an outer side by 0.3 Tr in the tire width direction from the tread surface position along the tire profile;
• in the tire see-through plan view, an inclination angle of the cord of the outermost carcass layer in the tire radial direction with respect to the tire width direction in a region in the tire width direction between the second reference point on one side from the tire equatorial plane as a boundary in the tire width direction and an other second reference point on another side from the tire equatorial plane as the boundary in the tire width direction is −3° or more and 3° or less relative to an average value of an inclination angle of the cord of the outermost carcass layer with respect to the tire width direction at a position of the second reference point in the tire width direction and an inclination angle of the cord of the outermost carcass layer with respect to the tire width direction at a position of the other second reference point in the tire width direction.
