Abstract:
A tire has excellent wet performance without leading to a reduction in steering stability. The tire includes a tread portion and a pair of bead portions each with a bead core and a bead filler disposed on the radial outside of the bead core. Tread rubber forming the tread portion includes a rubber composition including a rubber component (A) and, per 100 parts by mass of the rubber component (A), 5 to 50 parts by mass of at least one kind of thermoplastic resin (B) selected from the group consisting of C5-based resins, C5- to C9-based resins, C9-based resins, terpene-based resins, terpene-aromatic compound-based resins, rosin-based resins, dicyclopentadiene resins, and alkylphenol-based resins, and 20 to 120 parts by mass of a filler (C) including silica. The dynamic storage modulus (E′) of the bead filler exceeds 50 MPa.
