1. A pneumatic tire, comprising a sidewall and a carcass,
the sidewall comprising a laminate of two or more rubber layers including an inner sidewall layer (1), which is located closest to the carcass, and an outer sidewall layer (2), which constitutes an outer surface of the tire, the inner sidewall layer (1) comprising a rubber composition for an inner sidewall layer (1), the outer sidewall layer (2) comprising a rubber composition for an outer sidewall layer (2), the carcass comprising a carcass cord topped with a rubber composition for a carcass cord topping (3), the sidewall having a thickness of not more than 3.0 mm, the inner sidewall layer (1) having a thickness of 0.2 to 1.0 mm, the rubber composition for an inner sidewall layer (1) having a volume resistivity of not more than 5.0×107 Ω·cm, the rubber composition for an inner sidewall layer (1) and the rubber composition for an outer sidewall layer (2) satisfying the following relation (1), the rubber composition for a carcass cord topping (3) and the rubber composition for an inner sidewall layer (1) satisfying the following relation (2);
1.15≦E*(1)/E*(2)≦3.00 (1)1.00≦E*(1)/E*(3)≦2.50 (2) wherein E*(1) is a complex elastic modulus of the rubber composition for an inner sidewall layer (1), E*(2) is a complex elastic modulus of the rubber composition for an outer sidewall layer (2), and E*(3) is a complex elastic modulus of the rubber composition for a carcass cord topping (3). |
