Pneumatic tire

Pneumatic tire (1) with carcass (6) and sidewall rubbers (3G), wherein the sidewall rubber (3G) includes an inner layer (10) and an outer layer (11); the outer layer (11) has a complex elastic modulus E* higher than the inner layer (10) and a thickness that is (to) which is gradually increased from the maximum width position (Pm) towards the radially inner end; the inner layer (10) has a loss tangent tan ´ lower than that of the outer layer (11) and a thickness (ti) which is gradually reduced from the maximum width position (Pm) towards the radially inner end and gradually increased from this point to the radially outer end.
