PNEUMATIC TIRE

Provided is a pneumatic tire () including a tread rubber layer () and a carcass ply () formed by covering PET fiber cords with a coating rubber. The tread rubber layer () includes a rubber component, a resin component, and a filler. The rubber component includes an isoprene skeleton rubber and a styrene-butadiene rubber. The glass transition temperature of at least one type of the styrene-butadiene rubber is lower than −40° C. The resin component has a difference of the SP value relative to that of the isoprene skeleton rubber of 1.40 (cal/cm)or less. The tread rubber layer () satisfies formula (1): mass ratio of resin component/isoprene skeleton rubber ≥0.5. The carcass ply () has a total gauge of 1.2 mm or less. The carcass ply () satisfies formula (2): (A/B)/total fiber fineness ≥0.3.
