  • Publication number: 20220169082
    Abstract: In a tire, first and second ridge parts extending in a tire radial direction each have a central portion in the tire radial direction located on an inner side in the tire radial direction with respect to a central portion of the first ridge part in the tire radial direction are provided on an outer surface of a side wall part. A decorative area provided in an outer surface of the side wall part includes a dense area in which the first ridge part and the second ridge part face each other in the tire circumferential direction, and a sparse area in which either the first ridge parts or the second ridge parts face each other in the tire circumferential direction without interposing the other therebetween.

  • Patent number: 11325430
    Abstract: 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).
