Disclosed is an air-filled tire (1) provided with lugs formed by a central main groove (10), formed in a zigzag pattern around the circumference of the tire, and an outside main groove (20) that contains a void (AS). The lugs comprise a central lug (30), which has an outside wall surface (32), and an outside lug (40), which has an inside wall surface (41). The central lug (30) has a plurality of outwards protrusions (33), formed around the circumference of the tire, that protrude outwards in the width direction of the tire. The outside lug (40) has a plurality of inwards protrusions (43), formed around the circumference of the tire, that protrude inwards in the width direction of the tire. The pitch (P43) of the inwards protrusions (43) is less than that of the outwards protrusions (33). |
