Pneumatic tire

A pneumatic tire, comprising:

• a tread portion extending in a tire circumferential direction and having an annular shape;
• a pair of side wall portions disposed on both sides of the tread portion;
• a pair of bead portions disposed inward of the pair of side wall portions in a tire radial direction;
• a carcass layer mounted between the pair of bead portions;
• a plurality of belt layers disposed on an outer circumferential side of the carcass layer in the tread portion;
• a plurality of belt cover layers disposed on the outer circumferential side of the plurality of belt layers, the plurality of belt cover layers including edge cover layers locally covering both end portions of the belt layers in a tire lateral direction;
• circumferential grooves extending along the tire circumferential direction in a tire outer surface of the tread portion;
• and
• land portions defined between the circumferential grooves that are adjacent to each other in the tire lateral direction, wherein
• a number of the circumferential grooves is two or more,
• a number of the land portions is one or more,
• the one or more land portions include a center land portion continuously extending along an entire circumference of the tire and being disposed on a tire equator,
• a first sound absorbing member and a second sound absorbing member are adhered on radially outermost surfaces of the first sound absorbing member and the second sound absorbing member by an adhesive to a tire inner surface of the tread portion,
• the first sound absorbing member and the second sound absorbing member are porous and have a total volume ranging from 21% to 40% of a capacity of a tire cavity,
• the first sound absorbing member is disposed on one side in the tire lateral direction with respect to a position of 40% of a width Wc of the center land portion from one end portion of the center land portion on one side in the tire lateral direction to an other side in the tire lateral direction,
• the second sound absorbing member is disposed on the other side in the tire lateral direction with respect to a position of 40% of the width Wc of the center land portion from one end portion of the center land portion on the other side in the tire lateral direction to the one side in the tire lateral direction,
• the first sound absorbing member and the second sound absorbing member are separated from each other by 60% or more of the width Wc of the center land portion,
• a mounting direction on a vehicle is designated,
• the one side in the tire lateral direction is a vehicle inner side being an inner side with respect to the vehicle at a time of mounting on the vehicle, and the other side in the tire lateral direction is a vehicle outer side being an outer side with respect to the vehicle at a time of mounting on the vehicle,
• a volume V1 of the first sound absorbing member is smaller than a volume V2 of the second sound absorbing member,
• a ratio of V2/V1 of the volume V1 of the first sound absorbing member and the volume V2 of the second sound absorbing member satisfies a relationship of 2<V2/V1<3.8,
• end portions of the first sound absorbing member and the second sound absorbing member on the outer side in the tire lateral direction are positioned inward in the tire lateral direction with respect to end portions of the plurality of belt layers on the outer side in the tire lateral direction,
• at least one of the first sound absorbing member or the second sound absorbing member overlaps with the center land portion, and an amount of overlap of the at least one of the first sound absorbing member or the second sound absorbing member with respect to the center land portion is set to be 40% or less of the width Wc of the center land portion, and
• one of the first sound absorbing member or the second sound absorbing member overlaps with at least one of the edge cover layers and an other one of the first sound absorbing member or the second sound absorbing member does not overlap with any of the edge cover layers.
