FIELD: machine building.

SUBSTANCE: invention relates to automotive industry. Pneumatic tire is provided with a central area (5), limited by a pair of central main grooves (3) in a zigzag pattern passing in the tread (2). Central area (5) is provided with one central narrow groove (10) continuously and in a zigzag pattern passing in the tire longitudinal direction at the tire equator (C), and central side grooves (11), which pass from the central main groove (3), intersecting the central narrow groove (10), and their end (11e) is located within the central area (5). Central side grooves (11) comprise a main section (12) passing from the central main groove (3) to the central narrow groove (10) zigzag apex (10t) and inclined in one direction relatively to the tire axial direction, and an additional section (13) passing from the zigzag apex (10t) to the end (11e) and inclined in the reverse direction relatively to the groove main part (12).
