Un outil agricole (1) comprend un corps de roue (3) avec une gorge périphérique (35), un pneumatique (5) avec un talon (53) faisant saillie radialement vers l'intérieur et un verrou radial bloquant le pneumatique (5) autour du corps de roue (3). Le talon (53) est conformé de manière à se loger dans la gorge (35) au montage du pneumatique (5) autour du corps de roue (3). Le verrou radial comprend un premier orifice (37) ménagé dans le corps de roue (3) débouchant d'une part dans la gorge (35) et d'autre part dans une face principale (31 ; 33) du corps de roue (3), au moins un second orifice (67) ménagé dans le talon (53) du pneumatique (5) et ouvert sensiblement en regard du premier orifice (37), et une goupille (7) disposée dans le premier orifice (37) et le second orifice (67).

A pneumatic tire (10) is configured by a resin tire frame member (20). An inner face of the tire frame member (20) is provided with an attachment section (42). The attachment section (42) is configured so as to attach a sound-absorbing material (44) inside the tire frame member (20). The sound-absorbing material (44) employs, for example, a spongey material, and the sound-absorbing material (44) is capable of absorbing sound.

[Problem to be Solved] To provide an airless tire that allows both good drainage performance and good durability to be achieved and allows uneven wear resistance to be improved. [Solution] An airless tire 1 is provided that includes a cylindrical tread ring 2 that has a ground contact surface 5. Multiple through holes 8 and a reinforcing body 11 are provided in the tread ring 2, the multiple through holes 8 penetrating the tread ring 2 in a thickness direction of the tread ring 2. The multiple through holes 8 are arranged at intervals along a tire circumferential direction. The reinforcing body 11 includes a first reinforcing body 12 that extends in the tire circumferential direction in regions between adjacent through holes 8. Both ends (12e) of the first reinforcing body 12 in the tire circumferential direction terminate without being exposed from inner peripheral surfaces of the through holes 8.

[Problem to be solved] To provide an airless tire that has a small rolling resistance.

[Solution] An airless tire 1 is provided that includes a cylindrical tread ring 2 that has a ground contact surface (2a). The tread ring 2 has therein a reinforcing body 6. The reinforcing body 6 includes an annular first reinforcing cord layer 7 that extends in a tire circumferential direction, an annular second reinforcing cord layer 8 that is arranged on a tire radial direction inner side of the first reinforcing cord layer 7 and extends in the tire circumferential direction, and a shear layer 9 that is formed of an elastomer and is arranged between the first reinforcing cord layer 7 and the second reinforcing cord layer 8. The shear layer 9 includes a first portion 10 and a second portion 11, a loss tangent (tanδ) and a shear modulus (Ee) (unit: MPa) of the first portion 10 at a temperature of 30 °C satisfying the following Equations (1) and (2), and the second portion 11 being formed of a material different from the first portion 10. $$\mathrm{tan\delta }\leqq 0.06$$ $$\mathrm{Ee}/\mathrm{tan\delta }\geqq 1500$$

A non-pneumatic tire includes:a ring member (14) including an inner cylinder (12) externally covering an attachment body (11) to be attached to an axle and an outer cylinder (13) surrounding the inner cylinder (12) from a tire radial outer side; a plurality of connecting members (15) arranged along a tire circumferential direction between the inner cylinder (12) and the outer cylinder (13) and connecting the two cylinders to each other; and a tread member (16) made of vulcanized rubber and located on a tire radial outer side of the outer cylinder (13), wherein at least one part of the outer cylinder (13) and the plurality of connecting members (15) are integrally formed of a synthetic resin material, and an adhesion layer (25) containing a cyanoacrylate-based adhesive agent is located between the tread member (16) and the outer cylinder (13) having an amino group in a surface thereof.

A tire (10) includes: a tire frame member (12) that is made of a resin material and that includes bead portions (16), side portions (18) that is connected to tire radial direction outer sides of the respective bead portions (16), and a crown portion (26), on which a tread (32) is disposed, connected to tire width direction inner sides of the respective side portions (18) and on which a tread(32) is disposed; and reinforcing layers (14) of a reinforcing material (30) covered by a resin material, that are provided to at least the side portions (18) and that are disposed in a row around a tire circumferential direction.

A puncture resistant tube for a bicycle tire fitted to a rim of a bicycle wheel includes a tube body inserted into the bicycle tire along a tube insertion recess formed within the bicycle tire and an elastic recess depressed into the tube body adjacent to the portion of the bicycle tire to be fitted to the rim. When the portion of the bicycle tire to be fitted to the rim is shrunk by external force, elastic force is accumulated in the portion of the tube body surrounding the elastic recess while the elastic recess is being shrunk. When the bicycle tire is completely fitted to the rim, the elastic recess is restored to the original shape thereof by the accumulated elastic force, whereby the portion of the tire fitted to the rim is restored to the original shape thereof.

A renewed solid tire (26, 30, 48), comprising a worn solid tire (16) including a remaining rubber layer (20), and a room temperature-setting polyurethane elastomer layer (24) which is provided on an outer circumferential surface (22) of the rubber layer.
