Abstract: A pneumatic tire includes a tread portion provided with a pair of central blocks arranged on both sides of a tire equator. Each of the central blocks includes a ground contacting face having an axially inner block edge facing the tire equator. The inner block edge extends in a V-shaped manner including a first inclined edge and a second inclined edge inclined in an opposite direction to the first inclined edge. The second inclined edge has a circumferential length shorter than a circumferential length of the first inclined edge. Each of the central blocks includes a first portion having the first inclined edge and a second portion having the second inclined edge. The second portion of the central block includes an end wall at an opposite side to the first portion. The end wall includes a stepwise wall extending in steps toward a groove bottom.

Abstract: The purpose of the present invention is to improve running performance in rocky areas. Provided is a pneumatic tire in which is formed a shoulder block in which first shoulder blocks and second shoulder blocks are alternately aligned. Each first shoulder block has a first edge that is on the outer side in a tire axial direction of a tread surface of the first shoulder block. Each second shoulder block has a second edge that is positioned on the outer side in the tire axial direction of a tread surface of the second shoulder block and more toward the inner side in the tire axial direction than the first edge.

Abstract: A tire 1 comprises a tread portion 2 comprising shoulder blocks 3 and crown blocks 4. The shoulder blocks 3 each has a ground contacting surface (3t) comprising an axially outer portion 6 extending axially inwardly from one of tread edges (Te) and a steeply oblique portion 7 extending axially inwardly from the axially outer portion 6 with a larger inclination angle with respect to the tire axial direction than the axially outer portion 6. The crown blocks 4 each has a ground contacting surface (4t) comprising a first oblique portion 10 inclined oppositely to the steeply oblique portion 7 and a second oblique portion 11 extending from and obliquely and oppositely to the first oblique portion 10. In a development view of the tread portion 2, longitudinal directions of the steeply oblique portion 7 and the first oblique portion 10 intersect at an angle from 70 to 110 degrees.

Abstract: A pneumatic tire includes sidewall portions, at least one of which is provided in the outer surface thereof with an axially outwardly protruding protector. The protector is composed of patterned unit protrusions arranged at intervals in the tire circumferential direction. Each patterned unit protrusion includes a first protruding portion and a second protruding portion which extend in a tire radial direction and spaced apart from each other in the tire circumferential direction, and a third protruding portion connecting between the first and second protruding portions. The radial dimension L1 of the first protruding portion is more than the radial dimension L2 of the second protruding portion.
