Provided is a pneumatic tire. A band-like sound absorptive member is fixed to the inner surface of a tread portion along the tire circumferential direction. An end portion in the tire width direction of the sound absorptive member is located on the outer side in the tire width direction with respect to a shoulder main groove located on the outermost side in the tire width direction. A width W of the sound absorptive member in the tire width direction and a tread development width TDW of the tread portion satisfy a relationship of 0.65≤(W/TDW)≤0.90. The width W of the sound absorptive member and a belt width W of a first belt ply having the maximum width of a belt layer satisfy a relationship of 0.70≤(WW)≤0.95.
