A puncture resistant mute explosion-proof cushion for a tyre and a wheel thereof are provided. The explosion-proof cushion is annular, received in the tyre and made of composite nano vinyl acetate copolymer. The explosion-proof cushion includes an inner ring and an outer ring wrapped on the inner ring; when the explosion-proof cushion is installed in the tyre, the outer ring is attached to a top surface and a side surface of an inner wall of the tyre, and a height from the inner ring to the outer ring along a radial direction of the explosion-proof cushion is less than a height of the side surface of the inner wall of the tyre. The explosion-proof cushion of the present disclosure can improve comfort during ordinary driving of the tyre, and simultaneously can protect an integral structure of the wheel when the tyre runs under a condition of a tyre burst.

A depth gauge wheel for a row planter. The depth gauge wheel sets the planting depth for the seeds planted by the row planter. The depth gauge wheel sets planting depth by setting the cutting depth of the disk opener of the row planter. The depth gauge wheel also scrapes mud from the disk blade of the disk opener. The depth gauge wheel includes a rim, a tire attached to the rim and a ring attached to the rim. The tire contacts the surface of the ground to set the cutting depth of the disk opener and the ring scrapes mud from the disk blade of the disk opener.

An improved wheel for a mobility apparatus designed is disclosed herein. The wheel conforms to obstacles in the ground, creating a smoother walking experience. The inner web of a tire of the wheel preferably consists of polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles. The tire's inner core preferably consists of a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

The present disclosure relates to a method and manufacturing method for a tire tread composition having absorption properties with high electric conductivity and excellent wear resistance. Specifically, the present disclosure relates to the fabrication of a tire composition to be used as a non-pneumatic tire, the tire composition can be used as a mobile electrode with a water supply means that can identify the location of defects in the buried conductor using the tire electrode manufacturing with improved conductivity and contact resistance with the ground even though the tire compound has wear resistance by lowering the water swelling rate compared to the previous technology.

There is provided a non-pneumatic tire (1), which includes an attachment body (11) that is attached to an axle, a ring-shaped body (13) that surrounds the attachment body (11) from an outside in a tire radial direction, a connection member (15) that displaceably connects the attachment body (11) and the ring-shaped body (13) to each other, and a cylindrical tread member (16) that is externally mounted on the ring-shaped body (13), in which the tread member (16) includes a base rubber portion (41) that is positioned at an inside in the tire radial direction, and a cap rubber portion (42) that is positioned at an outside of the base rubber portion (41) in the tire radial direction, and in which the rigidity of the base rubber portion (41) is lower than the rigidity of the cap rubber portion (42).

An agricultural implement comprises a wheel body with a peripheral groove, a tire with a bead projecting radially inward, and a radial lock which locks the tire around the wheel body. The bead is shaped so as to be housed in the groove when the tire is mounted around the wheel body. The radial lock comprises a first aperture formed in the wheel body, opening into the groove on the one hand and onto a main face of the wheel body on the other hand, at least a second aperture formed in the bead of the tire, opening substantially facing the first aperture, and a pin placed in the first aperture and the second aperture.

A wheel assembly and method of assembling the same for use with an airless or non-pneumatic tyre. The assembly includes a rim member and at least one locking or retaining member. The rim member includes a first portion at least part of which is adapted to be attached to an axle in use, and at least part of the locking member is configured to detachably attach to at least part of the first portion of the rim member. Attachment to the rim member assists in retaining the tyre in position on rim member and/or the wheel assembly in use.

A non-pneumatic tire (1) of the present invention is provided with: an attachment body (11) attached to an axle; an outer cylindrical body (13) which surrounds the attachment body (11) from the outside in a tire radial direction; a coupling member (15) which displaceably couples the attachment body (11) and the outer cylindrical body (13); a cylindrical tread member (16) which is wrapped externally around the outer cylindrical body (13); and a protective member (41) which covers a side surface in a tire width direction (H) of the outer cylindrical body (13) from the outside in the tire width direction (H).

To provide a rubber compound for tires, a pneumatic tire and an airless tire capable of improving the steering stability of the tire while exerting excellent low fuel consumption performance. A rubber compound for tires characterized in that, of vulcanized rubber's physical properties, a complex elastic modulus E*.sub.70 (unit: MPa) and a loss tangent tanδ.sub.70 under initial strain of 10%, dynamic strain of 2% and temperature of 70 degrees C., satisfy 90<E.sub.70<250, and E*.sub.70/tan δ.sub.70>800. A pneumatic tire provided with a rubber member made of the above-mentioned rubber compound. An airless tire provided with a rubber member made of the above-mentioned rubber compound. An airless tire provided in a tread ring with a shear rubber layer made of the above-mentioned rubber compound.
