Document Type and Number:
WIPO Patent Application WO/2016/194386
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a tire in which rolling resistance is reduced both when at low temperatures and when at high temperatures and in which the difference in rolling resistance when at low temperatures and when at high temperatures is small. In order to solve this problem, a tire is provided with a tread section and a bead section comprising a pair of bead cores and a bead filler arranged on the radially outward side of the bead cores. The tire is characterized in that the tread rubber constituting the tread section comprises a rubber composition containing: a rubber component (A); 5-50 parts by mass of a thermoplastic resin (B) with respect to 100 parts by mass of the rubber component, said thermoplastic resin (B) comprising at least one resin selected from among C5 resins, C5-C9 resins, C9 resins, terpene resins, terpene-aromatic compound resins, rosin resins, dicyclopentadiene resins, and alkylphenol resins; and 20-120 parts by mass of a filler (C) containing silica. The tire is also characterized in that the dynamic storage modulus (E') of the bead filler is 50 MPa or less.
