Pneumatic tire

A pneumatic tire, comprising:

• a tread portion in which a plurality of main grooves are formed along a tire circumferential direction;
• a pair of sidewall portions respectively disposed on both sides of the tread portion;
• a pair of bead portions each disposed on an inner side in a tire radial direction of the respective one of the pair of sidewall portions;
• a carcass layer spanning between the pair of bead portions;
• a belt layer comprising at least one belt and disposed on an outer side in the tire radial direction of the carcass layer in the tread portion, each having a belt cord inclination angle with respect to the tire circumferential direction within a range of 20° or more and 35° or less;
• and
• a run-flat reinforced rubber extending from each sidewall portion to at least a portion of the tread portion;
• a sound absorptive member having a band shape, the sound absorptive member being fixed to an inner surface of the tread portion along the tire circumferential direction,
• a respective end portion in a tire width direction of the sound absorptive member being located on an outer side in the tire width direction with respect to the respective main groove on an outermost side in the tire width direction,
• a width W1 of the sound absorptive member in the tire width direction and a tread development width TDW of the tread portion between tread ground contact edges T satisfying a relationship of 0.65≤ (W1/TDW)≤0.90, and
• the width W1 of the sound absorptive member and a belt width W2 in the tire width direction of a belt having a maximum width in the belt layer satisfying a relationship of 0.70≤ (W1/W2)≤0.95, wherein
• in a tire meridian cross-section, an outermost end portion on the outer side in the tire radial direction of the respective run-flat reinforced rubber and the respective end portion of the sound absorptive member are separated in the tire width direction by a separation distance L1, and
• the separation distance L1 is in a range of 16 mm or more and 50 mm or less.
