Abstract:
Provided is a rubber composition that allows for manufacturing a tread rubber that is high in braking performance on a dry surface road and also high in braking performance even on a wet road surface such as a manhole surface that is slipperier than an asphalt road surface. The rubber composition is prepared by compounding a rubber component (A) including a natural rubber by 70mass% or more, and by further compounding, with the rubber component as 100 parts by mass: (B) at least one kind of thermoplastic resins selected from among C 5 -based resins, C 5 - to C 9 -based resins, C 9 -based resins, terpene-based resins, terpene-aromatic compound-based resins, rosin-based resins, dicyclopentadiene resins, and alkylphenol-based resins, at 5 parts by mass to 50 parts by mass; and (C) a filler including silica, at 20 parts by mass to 120 parts by mass, in which the filler (C) contains silica by 50mass% to 100mass%.
