The pneumatic tire includes block groups (G) formed by polygonal blocks (), which are arranged closely in a tread portion (). The polygonal blocks () are formed by grooves () including first groove () with a groove width (W) between the polygonal blocksneighboring with each other in the tire circumferential direction. The groove width (W) of the first grooves () is larger than a groove width (W) of second grooves () between the polygonal blocksneighboring with each other with a zigzag pattern.
