RUBBER COMPOSITION FOR TIRE AND TIRE

摘要

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* 50°C and a complex modulus G* 100°C satisfy the following formula (1): G* 100°C / G* 50°C > 0.85, an elongation at break EB 23°C and a loss tangent tan´ 50°C is 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.
