Patent number: 9663639Abstract: The present invention is a rubber composition for tire treads, of which the temperature of the peak position of the temperature curve of tan ? is ?16.0° C. or higher and ?6.0° C. or lower, tan ? at the peak position is larger than 1.13, tan ? at 0° C. is 0.95 or more, and the value obtained by dividing the absolute value of the difference between tan ? at ?5° C. and tan ? at 5° C. by the temperature difference between ?5° C. and 5° C. {|(tan ? at ?5° C.)?(tan ? at 5° C.)|/10} (/° C.) is smaller than 0.045/° C. The invention provides the rubber compositions for tire treads that more highly satisfy both low-heat-generation property and wet braking performance.Type: GrantFiled: June 4, 2013Date of Patent: May 30, 2017Assignee: BRIDGESTONE CORPORATIONInventor: Keisuke Kawashima
