Abstract:
A tire satisfying both of the low rolling resistance of the tire and the improvement of tire strength is provided. A tire including sidewall including a rubber composition for sidewall including a rubber composition including a rubber component including 35 to 65% by mass of NR and/or IR, 15 to 55% by mass of a modified BR and 0 to 50% by mass of other rubber and 20 to 40 parts by mass of filler, in which complex elastic modulus E* is 2.0 to 3.5 MPa and tan δ is less than 0.12; case in which cord is covered with a rubber composition for covering case cord including a rubber component including 50 to 80% by mass of NR and/or IR, 20 to 45% by mass of diene rubber of a modified SBR, a modified BR or ENR and 0 to 30% by mass of other rubber and 20 to 40 parts by mass of filler, in which E* is 2.0 to 3.5 MPa and tan δ is less than 0.12; and clinch including a rubber composition for clinch including a rubber component including 30 to 50% by mass of NR and/or IR, 15 to 70% by mass of a modified BR and 0 to 55% by mass of other rubber and 35 to 80 parts by mass of filler, in which E* is 4.5 to 9.0 MPa and tan δ is less than 0.12.
