Pneumatic tire

Abstract

Provided is a pneumatic tire in which not only the cutting resistance is enhanced but also the resistance to penetration of a foreign matter is improved without deterioration of the crack propagation resistance of an outermost belt layer. The pneumatic tire is a pneumatic tire 100 including a belt composed of at least three belt layers 103 on the tire radial-direction outer side of a carcass 102. In the pneumatic tire 100, a reinforcing material of at least an outermost belt layer 103c among the at least three belt layers 103 is a steel cord which has a layer-twisted structure including a core composed of two core filaments and a sheath composed of eight sheath filaments that are twisted together around the core, and a steel cord amount in the outermost belt layer 103c, which is represented by the following Equation (1), is 37 to 49: Steel cord diameter (mm)×Steel cord end count (steel cords/50 mm) (1).
