Abstract:
A color rubber composition for tires according to an embodiment contains a rubber component, a pigment other than black or white, a petroleum wax, and a white filler. The petroleum wax has a normal/iso ratio (mass ratio) of 70/30 to 90/10. The carbon number distribution for iso components in the whole petroleum wax is 1.0% or less for 25 or less carbon atoms, 4.0 to 8.0% for 26 to 32 carbon atoms, 5.0 to 15.0% for 33 to 44 carbon atoms, and 1.0% or more for 45 or more carbon atoms. The carbon number distribution for normal components in the whole petroleum wax is 5.0 to 18.0% for 25 or less carbon atoms, 40.0 to 48.0% for 26 to 32 carbon atoms, 15.0 to 27.5% for 33 to 44 carbon atoms, and 2.0% or more for 45 or more carbon atoms.
