A tire, comprising: a tire frame member formed of a resin material, the tire frame member including: a bead portion, a side portion that extends toward a tire radial direction outer side from the bead portion, and a crown portion that extends toward a tire width direction inner side from the side portion; and a tread formed of a rubber material, the tread being disposed at the tire radial direction outer side of the tire frame member, a plurality of circumferential direction grooves that extend in a tire circumferential direction being formed in a tread surface, and a groove width of a circumferential direction groove having a widest groove width along the tire width direction being within a range of from 5% to 15% of a ground contact width of the tread surface, wherein the ground contact ends of a top tread are regions that are loaded with a maximum load performance when the tire is mounted to a standard rim complying with the JATMA YEAR BOOK (from the Japan Automobile Tire Manufacturers Association, 2015 edition) and charged with air pressure to 100% of an air pressure corresponding with the maximum load performance (the bold-text load in the table of internal pressure against load performance) in the JATMA YEAR BOOK for the employed size and ply rating; the ground contact width is a dimension measured along the tire width direction from one of the ground contact ends to another of the ground contact ends; the resin material of the tire frame member is a thermoplastic resin or a thermoplastic elastomer, a plurality of tire structure members are bonded together to form the tire frame member; a bonding portion that bonds the plurality of the tire structure members together is formed continuously in the tire circumferential direction at the crown portion; viewed in the tire radial direction, the circumferential direction groove having the widest groove width is disposed at a location that is separated in the tire width direction from the bonding portion, characterized in that a belt layer is provided at an outer periphery face of the crown portion, and the belt layer is formed by winding cords covered with resin in helical patterns along the tire circumferential direction. a tire frame member formed of a resin material, the tire frame member including: a bead portion, a side portion that extends toward a tire radial direction outer side from the bead portion, and a crown portion that extends toward a tire width direction inner side from the side portion; and a bead portion, a side portion that extends toward a tire radial direction outer side from the bead portion, and a crown portion that extends toward a tire width direction inner side from the side portion; and a tread formed of a rubber material, the tread being disposed at the tire radial direction outer side of the tire frame member, a plurality of circumferential direction grooves that extend in a tire circumferential direction being formed in a tread surface, and a groove width of a circumferential direction groove having a widest groove width along the tire width direction being within a range of from 5% to 15% of a ground contact width of the tread surface, wherein the ground contact ends of a top tread are regions that are loaded with a maximum load performance when the tire is mounted to a standard rim complying with the JATMA YEAR BOOK (from the Japan Automobile Tire Manufacturers Association, 2015 edition) and charged with air pressure to 100% of an air pressure corresponding with the maximum load performance (the bold-text load in the table of internal pressure against load performance) in the JATMA YEAR BOOK for the employed size and ply rating; the ground contact width is a dimension measured along the tire width direction from one of the ground contact ends to another of the ground contact ends; the resin material of the tire frame member is a thermoplastic resin or a thermoplastic elastomer, a plurality of tire structure members are bonded together to form the tire frame member; a bonding portion that bonds the plurality of the tire structure members together is formed continuously in the tire circumferential direction at the crown portion; viewed in the tire radial direction, the circumferential direction groove having the widest groove width is disposed at a location that is separated in the tire width direction from the bonding portion, characterized in that a belt layer is provided at an outer periphery face of the crown portion, and the belt layer is formed by winding cords covered with resin in helical patterns along the tire circumferential direction.
