Pneumatic Tire

In a pneumatic tire having a point-symmetric structure block pattern, narrow and wide outer blocks having different outer end positions in the lateral direction are alternately arranged in the circumferential direction. Among side blocks provided in a side region, large and small blocks are disposed respectively on the outer sides of the narrow and wide outer blocks in the lateral direction. The lateral and side grooves are continuous such that the groove width of the side groove connected to the wide portion of the lateral groove where the outer block converges toward the inner side in the radial direction, and the groove width of the side portion connected to the narrow portion of the lateral groove where the outer block widens toward the inner side in the radial direction, and the side block is tapered with an inner portion block width in the radial direction converges toward the wide portion.
