In order to provide a tire in which on-ice performance can be improved while ensuring adequate on-snow performance and handling performance, there are provided: a zigzag-shaped center groove (12) formed continuously along the circumference direction of the tire (10) on the widthwise inside of the tire on the surface of the tread (11) of the tire, the center groove (12) extending so as to be inclined towards one of the widthwise end sections of the tire and then folding back and being inclined towards the other widthwise end section of the tire; zigzag-shaped shoulder grooves (12) formed continuously along the circumference direction of the tire on the widthwise outside of the tire, the shoulder grooves (13) extending so as to be inclined towards one widthwise end section of the tire and then folding back and being inclined towards the other widthwise end section of the tire; and lug grooves (14a, 14b) formed so as to link the center groove (12) and the shoulder grooves (13), the angle formed between the direction of extension of the lug grooves (14a, 14b) and the direction parallel to the width direction of the tire being greater than the angle formed between the center groove (12) and the direction parallel to the width direction of the tire, and the angle formed between the shoulder grooves and the direction parallel to the width direction of the tire. |
