Abstract
In a pneumatic tire, a sidewall portion includes a plurality of projecting portions projecting in a tire width-direction. The projecting portions are placed such that at least portions of the projecting portions are superposed on one of a plurality of blocks in a tire radial-direction as viewed from a tire width-direction. At least one of the plurality of projecting portions includes at least one opening. A total sum of an opening area of the opening is equal to or smaller than an actual area of the projecting portion in the at least one of the projecting portions.
Claims19
A pneumatic tire comprising:
- a sidewall portion extending in a tire radial-direction;
- and
- a tread portion having a tread surface on an outer side in the tire radial-direction and connected to an outer end of the sidewall portion in the tire radial-direction, wherein
- the tread portion includes a plurality of grooves extending to an outer end in a tire width-direction, and a plurality of blocks arranged in a tire circumferential-direction by being defined by the plurality of grooves,
- the sidewall portion includes a plurality of projecting portions projecting in the tire width-direction,
- the projecting portions are placed such that at least portions of the projecting portions are superposed on one of the plurality of blocks in the tire radial-direction as viewed from the tire width-direction,
- at least one of the plurality of projecting portions includes at least one opening, and
- a total sum of an opening area of the opening is equal to or smaller than an actual area of the projecting portion in the at least one of the projecting portions,
- the at least one opening includes a first side surface placed on a first side in a tire circumferential-direction, and a second side surface placed on a second side opposite the first side in the tire circumferential-direction, and
- an angle formed between the second side surface and a surface of the projecting portion is closer to a right angle than an angle formed between the first side surface and the surface of the projecting portion.
