The bead portion of the pneumatic tire includes a bead structure having a bead core composed of a bead cord, and an annular plate which extends to the tire circumferential direction and is formed of a resin material. The annular plate has a planar first annular ring portion extending to the tire circumferential direction and a second annular ring portion positioned outside the tire radial direction of the first annular portion and extending to the tire circumferential direction, the first annular portion is provided along the bead structure, and the second annular portion is further inclined to the outside in tire width direction of the first annular portion.

A tire including a circular tire frame formed of a resin material that includes a thermoplastic resin and fibers.

An agricultural tool used to form furrows includes a generally cylindrical support and a plurality of tires. Each tire includes a sole by way of which the tire is mounted on the support, a tread opposite the sole (3) and two sidewalls that connect the tread to the sole. The sole, the tread (5) and the sidewalls jointly form a deformable casing. The tread of at least one of the plurality of tires has a generally domed shape. The sidewalls of this tire are generally inclined radially. The domed shape of the tread and the inclination of the sidewalls are such that the deformation of the casing urges the sole axially outward.

A tire 10 includes a resin tire case 17, a belt layer 12, a corner filler member 40, and a tread 38. The resin tire case 17 is made from resin and includes a bead portion 14, a side portion 16, and a crown portion 18. The belt layer 12 is provided at the tire radial direction outside of the crown portion 18 and is formed by winding a covered reinforcing cord 28 configured by covering a reinforcing cord 24 with resin in a tire circumferential direction so as to form a spiral pattern. The corner filler member 40 is provided at the radial direction outside of the crown portion 18 so as to fill a corner recess formed between an outer face 18A of the crown portion 18 and an upright-projecting face of the belt layer 12. The tread 38 covers the crown portion 18 from the tire radial direction outside of the belt layer 12.

Provided is a tire that has excellent high-speed durability even though a resin material is used therein. The tire includes a tire frame (10) having an annular shape, a reinforcement layer (20) located outward of the tire frame (10) in a tire radial direction, and tread rubber (30) located outward of the reinforcement layer (20) in the tire radial direction. The reinforcement layer (20) includes a reinforcement member (21) that is coated with a resin composition containing from 50 mass % to 100 mass % of a resin material. The tread rubber (30) has a loss tangent (tan .sub.60 C.) during 1% strain at 60 C. and a storage modulus (E.sub.30 C. (MPa)) during 1% strain at 30 C. that satisfy a relationship in a formula: 27.5tan .sub.60 C.+1.125E.sub.30 C.27.5tan .sub.60 C.+11.25.
