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 EB23° C. and a loss tangent tanδ50° 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.
