Abstract
A pneumatic tire includes a carcass layer, a belt layer disposed outward of the carcass layer, a tread rubber disposed outward of the belt layer in a tire radial direction, sidewall rubbers disposed outward of the carcass layer in a tire width direction, and protectors disposed in regions from tire ground contact edges to maximum tire width positions and protruding from tire profiles. The protectors have a rubber hardness Hs_p in a range of 50≦Hs_p≦60, an elongation at break Eb_p in a range of 500%≦Eb_p≦700%, and an elastic modulus E_p in a range of 3.4 MPa≦E_p≦7.0 MPa.
