Pneumatic Tire

In a pneumatic tire, a pair of first center blocks and two or more second center blocks are alternately arranged in the tire circumferential direction to form a block row of a center land portion. Additionally, the block row of the center land portion is obtained by coupling in a row in the tire circumferential direction and in a zigzag shape via coupling grooves each including a groove bottom portion shallower than first and second inclined lug grooves.
