  • Publication number: 20200180360
    Abstract: A tire has a rim protector which is formed at a sidewall and which constitutes, an annular protrusion that extends in a tire circumferential direction. The rim protector has not less than two recesses that extend toward the tread region from a location toward the bead region in such fashion as to be directed toward a location in a second direction from a location in a first, direction in the tire circumferential direction, the not less than two recesses being arranged with spaces therebetween in the tire circumferential direction. A mutually adjacent pair of recesses among the not less than two recesses are in a positional relationship such that they partially overlap as seen when projected onto a virtual plane perpendicular to a tire radial direction.

  • Patent number: 10625541
    Abstract: A pneumatic tire includes first and second side blocks formed respectively on a side portion such that the first and second side blocks extend toward the inside in a tire radial direction from a tread shoulder portion. The first and second side blocks are arranged alternately in a tire circumferential direction. The first side block has a recessed portion formed so as to be indented with respect to a side surface. In a first region, the second side block projects outwardly in a tire width direction more than the first side block. In a second region disposed inner side than the first region, the first side block projects outwardly in the tire width direction more than the second side block. In a third region disposed inner side than the second region, the second side block projects outwardly in the tire width direction more than the first side block.
