PNEUMATIC TIRE

Provided is a pneumatic tire having excellent ride comfort and steering stability during high speed running. The pneumatic tire is a pneumatic tire including a tread portion and a belt layer, wherein the belt layer includes reinforcing cords made of a steel monofilament and covered with a rubber composition, and the number e of the reinforcing cords arranged (cords) per 5 cm in a tire width direction, a thickness G (mm) of the tread portion, and a complex elastic modulus E (MPa) measured for the rubber composition under conditions of temperature: 70°C, initial strain: 5%, dynamic strain: ±1%, frequency: 10 Hz, and deformation mode: stretch, satisfy the following (Expression 1). e ÷ G × E * ≥ 70
