  "textContent": "A pneumatic tire comprises shoulder land zones (5) and middle land zones (6) divided by shoulder main grooves (3) and a crown main groove (7). The shoulder land zone (5) is divided by shoulder lateral grooves (8) into shoulder blocks (20). The middle land zone (6) is formed as a circumferential rib (21) in substance. The middle land zone is provided with first (11) and second (12) middle outward slots which extend from the shoulder main groove (3) toward the axially inside beyond the widthwise center line of the middle land zone (6), while gradually decreasing the width and inclining with respect to the tire axial direction at an angle ¸1 and an angle ¸2 (¸2 > ¸1), respectively, and terminate within the middle land zone (6). The open ends of the first and second middle outward slots (11,12) respectively face the open ends of the shoulder lateral grooves (8) at the shoulder main groove (6).",
