Abstract
A pneumatic tire includes an innerliner and a tie rubber. A rubber composition for an innerliner constituting the innerliner includes from 25 to 75 parts by mass of a carbon black having a nitrogen adsorption specific surface area from 25 to 95 m2/g, from 1 to 13 parts by mass of a resin, and from 0.1 to 1.8 parts by mass of zinc oxide, per 100 parts by mass of a diene rubber containing from 50 to 100 parts by mass of halogenated butyl rubber, and the dynamic storage modulus at −45° C. of the rubber composition is not greater than 600 Mpa.
Claims9
A pneumatic tire comprising:
- an innerliner;
- and
- a tie rubber comprising a tie rubber composition, the tie rubber composition including a first diene rubber selected only from a natural rubber, an isoprene rubber, a a styrene-butadiene rubber, or mixtures of two or more rubbers selected from the natural rubber, the isoprene rubber and the styrene-butadiene rubber,
- an innerliner rubber composition constituting the innerliner including
- from 25 to 75 parts by mass of a carbon black having a nitrogen adsorption specific surface area from 25 to 95 m2/g,
- a total resin content of the innerliner rubber composition of from 1 to 10 parts by mass, and
- from 0.1 to 1.8 parts by mass of zinc oxide,
- per 100 parts by mass of a second diene rubber containing from 50 to 100 parts by mass of halogenated butyl rubber, and
- a dynamic storage modulus at −45° C. of the innerliner rubber composition is not greater than 600 Mpa.
