Abstract
An object of the present invention is to provide a rubber composition for tire which has less performance change with respect to a temperature change at a high temperature region and has less performance change with respect to a road surface change from a wet road surface to a dry road surface, and a tire which has a tire member composed of the rubber composition for tire. The rubber composition for tire of the present invention is a rubber composition for tire in which a complex modulus G*and a complex modulus G*satisfy the following formula (1): G*/G*>0.85, an elongation at break EBand a loss tangent tanδis not less than 0.12. The present invention also refers to a tire which has a tire member composed of the rubber composition for tire.
