Abstract: A pneumatic tire comprises a sidewall portion is provided in the outer surface with a circumferentially continuous or discontinuous serrated zone in which radially extending serration ridges are arranged circumferentially of the tire. The serration ridges are grouped into circumferentially successively arranged groups each consisting of serration ridges whose angles θ with respect to the respective tire radial directions are different from each other, and gradually increased toward one circumferential direction. Each group has an equally-spaced position at which the serration ridges are equally spaced in the tire circumferential direction.

Abstract: A rim guard of a tire has a top, an inner surface, and an outer surface. A contour of the inner surface is represented by a circular arc, and the circular arc has a radius of not less than 20 mm and not greater than 30 mm. A contour of the outer surface is represented by a circular arc, and the circular arc has a radius of not less than 100 mm and not greater than 500 mm. In a radial direction, a position of an outer edge of the outer surface coincides with a cross-sectional width specified position, or the outer edge of the outer surface is located outward of the cross-sectional width specified position.

Abstract: A tire 2 includes a tie gum 24 between a carcass 12 and each chafer 22. In the tire 2, an inner liner 20 is formed from a thermoplastic elastomer composition including a styrene-isobutylene-styrene block copolymer. The inner liner 20 has a thickness of not greater than 1.5 mm. The tie gum 24 joins the inner liner 20 and the chafer 22 and has a volume resistivity of not greater than 108 Ω·cm.

Abstract: According to a tire comprising a CFRP comprising a matrix resin and a carbon fiber, in which the matrix resin comprises a resin component comprising 20 to 80% by mass of an epoxy resin and 20 to 80% by mass of a functional group-modified acrylonitrile butadiene copolymer, it is possible to provide a tire which is lightened while maintaining the strength of a tire with a steel cord and/or a bead wire.
