Due to the shape of the first bulging portion 110 and the second bulging portion 120, the groove portion 200 forms a spiral inside the circumferential groove 20.
- the bottom surface of the groove portion 200 communicates with the side surface 111 of the first bulging portion 110 as one continuous surface. Further, the bottom surface of the groove portion 200 communicates with the side surface 121 of the second bulging portion 120 as one continuous surface. That is, the bottom surface of the groove part 200 does not have a portion where irregularities and ridge lines are formed, and has a shape that prevents the flow of rainwater entering the groove part 200 as much as possible.
- a first bulging portion 110 is formed between the second protruding portions 120, grooves 200 extending in the tire circumferential direction D C is formed with a plurality.
- First bulging portion 110, in the tread surface view of the pneumatic tire 10 has the shape of a narrowing end narrows the size of the tread width direction D T taken to go to the first direction in the tire circumferential direction D C.

- the rainwater flowing through the groove 200 flows spirally from the bottom surface of the groove 200 toward the side surface 111 of the first bulging portion 110 and the side surface 121 of the second bulging portion 120. For this reason, rainwater that has entered the circumferential groove 20 flows smoothly without causing a large turbulent flow inside the circumferential groove 20. That is, even when the lug groove component is reduced as in the pneumatic tire 10, sufficient drainage can be achieved.
- the side surface 111 of the first bulging portion 110 has an arc shape that is recessed toward the side wall 21. Further, the side surface 121 of the second bulging portion 120 has an arc shape that is recessed toward the side wall 22. For this reason, the flow of rainwater entering the circumferential groove 20 is more likely to be spiral, and the drainage is further improved.
- the wide side of the end portion 110b of the first bulging portion 110 (second bulging portion 120) (end 120b) is located in the tire radial direction D R inward from tread surface of the land portion 30.
- the narrow side of the end portion 110a of the first bulging portion 110 (second bulging portion 120) (end 110b) are located at substantially the same height in the tread and the tire radial direction D R of the land portion 30 To do.
- the bottom surface of the groove portion 200 communicates with the side surface 111 of the first bulging portion 110 as one continuous surface, and communicates with the side surface 121 of the second bulging portion 120 as one continuous surface.
- the water guided in the first direction along the direction in which the groove portion 200 extends reaches the wide end portion 110b of the first bulge portion 110, and then the water on the narrow side of the first bulge portion 110. It is blocked by the end 110 a and is guided from one side wall 21 of the circumferential groove 20 to the other side wall 22 of the circumferential groove 20. Further, the water is blocked by the narrow-side end portion 120a of the second bulging portion 120 and the other side wall 22 of the circumferential groove 20, and is guided in the first direction as a spiral flow. By continuing such a flow of water, the flow of water becomes spiral.
- the bottom surface of the groove portion 200 communicates with the side surface 111 of the first bulging portion 110 as one continuous surface and one continuous surface with the side surface 121 of the second bulging portion 120. Although it communicated as a surface, the bottom surface of the groove part 200 does not necessarily have to be communicated as one continuous surface as described above, and there may be a portion where some unevenness and a ridge line are formed.
- the side surface 111 of the first bulge portion 110 and the side surface 121 of the second bulge portion 120 are arcuate, but the side surfaces are not necessarily arcuate, and the tread width direction D in a cross section along the T and the tire radial direction D R, it may be linear.
- a tire having sufficient drainage can be provided even when the lug groove component is reduced.
