Disclosed is a pneumatic tire that achieves a high level of both performance on ice and performance on snow. The pneumatic tire is provided with a block group (G) comprising polygonal blocks (10) that are densely disposed at a tread section (1), and the width (W9a) of the grooves (9) that partition the polygonal blocks (10) at the groove sections (9a) that are sandwiched between adjacent polygonal blocks (10) in the circumferential direction of the tire is greater than the width (W9b) of the grooves (9) that partition the polygonal blocks (10) at the groove sections (9b) that are sandwiched between polygonal blocks (10) that are in a staggered relationship. L'invention concerne un pneumatique qui assure à la fois, et à haut niveau, des performances sur glace et sur neige. Ce pneumatique est équipé d'un groupe de blocs (G) constitué de la disposition de façon concentrée de blocs polygonaux (10) sur une partie bande de roulement (1); et présente une largeur de rainure (W9a) de la portion rainure (9a) qui se trouve entre les blocs polygonaux (10) adjacents dans la direction périphérique du pneumatique, plus large que la largeur de rainure (W9b) de la portion rainure (9b) qui se trouve entre les blocs polygonaux (10) en zigzag, parmi des rainures (9) qui délimitent les blocs polygonaux (10).
