Abstract: A tread portion is provided with a first block and a second block, which protrudes outward in a tire width direction more than the first block, alternately in a tire circumferential direction in a shoulder region. A first projection is provided in an outer side of the first block, and a second projection is provided in an outer side of the second block. An outside end of the second projection is connected to a side surface of the second block and is arranged closer to an outer side in the tire diametrical direction than an outside end of the first projection. An angle ?1 formed by a side surface of the first projection and a surface of the side wall portion is greater than an angle ?2 formed by a side surface of the second projection and the surface of the side wall portion.

Abstract: A pneumatic tire includes a plurality of center lug grooves disposed at intervals in a tire circumferential direction that extend crossing a tire equator line and include a first groove turning portion and a second groove turning portion; a plurality of shoulder lug grooves disposed in the intervals between the plurality of center lug grooves in the tire circumferential direction extending outward in the tire width direction, an inner end in the tire width direction being disposed outward of an end of the center lug groove in the tire width direction; a pair of circumferential main grooves to which the ends of the center lug grooves and the inner ends of the plurality of shoulder lug grooves in the tire width direction alternately connect; and a circumferential secondary groove disposed around the entire circumference of the pneumatic tire with a wave-like shape.

Abstract: A pneumatic tire includes a tread portion having a pair of central block rows arranged on both sides of a tire equator. Each of the central block rows includes a plurality of central blocks arranged in a circumferential direction of the tire. Each of the central blocks includes a ground contacting face with an axially inner block edge facing the tire equator. The inner block edge includes a first inclined edge and a second inclined edge inclined in an opposite direction to the first inclined edge so that the inner block edge protrudes toward the tire equator. The first inclined edge includes a first circular arc portion with a center located on the side of the tire equator.
