摘要:
A pneumatic tire includes a band-shaped sound absorbing member bonded along a tire circumferential direction to the tire inner surface in a tread portion; at least one full cover layer covering the entire width of belt layers on the outer circumferential side of the belt layers; and a center cover layer disposed on the outer circumferential side of the full cover layer, the center cover layer locally covering the tire lateral direction center region of the belt layers; a width SW of the band-shaped sound absorbing member and a width BW of the belt layers satisfying a relationship SW/BW=0.3 to 0.8, and a width CW of the center cover layer and the width SW of the band-shaped sound absorbing member satisfying the relationship CW/SW=0.05 to 0.35.
