Abstract: To provide a pneumatic tire that provides improved driving performance on unpaved roads and cut resistance. High blocks and low blocks with different raised heights are provided as side blocks provided in a side region. One of the high blocks and one of the low blocks adjacent to each other in a tire circumferential direction are defined as a block pair. The high block and the low block included in the block pair are partially in contact with each other. Thus, a side groove between these blocks is a closed groove. In each block pair, a pair of contour lines (a first linear portion, a second linear portion, and a third linear portion) define edges on both sides, in the tire circumferential direction, of a top surface of each of the high block and the low block.

Abstract: A tire 1 includes a pair of crown circumferential grooves 30, a pair of shoulder circumferential grooves 31, a crown land portion 40, and a pair of middle land portions 41 and 42, the crown land portion 40 includes a main crown shallow groove 100 and at least two sub-crown shallow grooves 101 and 102 each extending so as to communicate with the crown circumferential groove 30 and the main crown shallow groove 100, the pair of middle land portions 41 and 42 include V-shaped slots 201 and 202, respectively, and the sub-crown shallow grooves 101 and 102 and the slots 201 and 202 are located so as to be substantially point-symmetrical about a midpoint between positions at which the adjacent sub-crown shallow grooves 101 and 102 communicate with the main crown shallow groove 100.
