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 θ1 formed by a side surface of the first projection and a surface of the side wall portion is greater than an angle θ2 formed by a side surface of the second projection and the surface of the side wall portion.
Claims15
A pneumatic tire comprising:
- a pair of bead portions;
- side wall portions which extend outward in a tire diametrical direction from the bead portions;
- and
- a tread portion which is connected to an outside end in the tire diametrical direction of each of the side wall portions,
- wherein the 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,
- wherein the side wall portion is provided with a first projection which is provided in an outer side in the tire width direction of the first block, and a second projection which is provided in an outer side in the tire width direction of the second block,
- wherein each of the first projection and the second projection extends in the tire diametrical direction,
- wherein an outside end in the tire diametrical direction 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 in the tire diametrical direction of the first projection, and
- wherein an angle θ1 formed by a side surface of the first projection and a surface of the side wall portion is larger than an angle θ2 formed by a side surface of the second projection and the surface of the side wall portion.
