Pneumatic radial tire with inner carcass ply E*1 different from outer carcass ply E*2

摘要

A pneumatic radial tire has a carcass composed of radially inner and outer carcass plies. A complex elastic modulus E*1 of the topping rubber of the inner carcass ply is different from a complex elastic modulus E*2 of the topping rubber of the outer carcass ply, and a ratio E*1/E*2 is 0.95 or lower or 1.05 or higher.
