Patent number: 11325430Abstract: A protrusion portion (110) of a pneumatic tire is formed by a plurality of protrusion parts (111) extended along a tire circumferential direction. The protrusion parts (111) are arranged with predetermined gaps therebetween so as to form a circle along the tire circumferential direction. A length (S1) of the protrusion part (111) in the tire circumferential direction is larger than a maximum width (W1) of the protrusion part (111) in a tire radial direction. In a tire side view, a narrow groove (200) extended along the tire circumferential direction is formed on a surface (111s) of the protrusion part (111).Type: GrantFiled: October 17, 2018Date of Patent: May 10, 2022Assignee: BRIDGESTONE CORPORATIONInventor: Shiho Kamada
