[PROBLEMS] To provide a rubber composition capable of obtaining high grip performance without impairing various tire performances such as fracture characteristics and wear resistance and factory workability when used in a tire tread, and pneumatic using the rubber composition Provide tires. The rubber component is represented by the following general formula (I): MX (I) (M is a metal cation of lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, radium, aluminum, iron, copper, tin, titanium, vanadium or manganese, and X is a counter anion for the metal cation. And a resin selected from a phenol resin, a terpene phenol resin, a C5 petroleum resin, a C9 petroleum resin, a C5 / C9 copolymer resin, a dicyclopentadiene resin, and a modified resin. And a pneumatic tire using the same. [Selection figure] None |
