    Abstract: A pneumatic tire includes undertread layer made of a rubber composition obtained by blending, per 100 parts by mass of diene rubber, 15 parts by mass to 45 parts by mass of carbon black having a nitrogen adsorption specific surface area N2SA of 20 m2/g to 85 m2/g and a DBP absorption of 90 mL/100 g to 200 mL/100 g, 3 parts by mass to 30 parts by mass of silica, and a silane coupling agent in an amount of 5 mass % to 15 mass % of the silica. A ratio is calculated based on a hardness Hu of an undertread rubber and an elastic modulus Ec and a hardness Hc of a cap tread rubber, is set to 110 to 140. A proportion iof a thickness G2 of the undertread layer to an under-groove rubber gauge G1, is set to 0.55 or more and 0.80 or less.
