A non-pneumatic tire includes beads, apexes, an inner liner, a cushion ply, a tread rubber, sidewall rubbers, and a first carcass ply; and further includes sidewall support layers and a crown support layer. The sidewall support layers are located at the locations of sidewalls and interposed between the inner liner and the first carcass ply. The crown support layer is located at the location of a crown, and interposed between the inner liner and the first carcass ply or between the first carcass ply and the cushion ply. Both ends of the crown support layer respectively extend toward the sidewalls and are partly overlapped with the sidewall support layers.

Tire includes a casing with an interior, and the casing has an inside diameter. A fill is provided in the interior of the casing. The fill includes a first layer and a second layer adjacent to the first layer. The first layer has an outside diameter and an inside diameter, and the outside diameter is the same as the inside diameter of the casing for contacting the casing. The first layer has a face and open voids. The open voids of the first layer have a first volume and are open to the face. The second layer has an outside diameter that is the same as the inside diameter of the first layer. The second layer has a face and open voids, and the open voids of the second layer have a respective first volume and are open to the face.

A non-pneumatic tire (100) having a pair of opposing annular support structures (102, 104) that extend circumferentially around the tire. Each support structure (102, 104) includes a radially-inner joint (120), a radially-outer joint (122), and a pair of support legs (132, 134) connected with a central joint portion (148). An annular band connects with the support structures (102, 104).

A non-pneumatic tire intended to be mounted on a rim and fitted to a lightweight vehicle, and the subject of the present invention is more specifically a tire element, which is able to be wound onto a rim. To increase the load-bearing capability, the tire element (1) has two stiffening portions (6) at least partially not joined together, and each stiffening portion (6) extends in the open main interior cavity (5), from a transition zone between the bead (4) and the sidewall (3) as far as the vicinity of the middle of the crown (2), and delimits, with a portion of tire element (7) facing the said stiffening portion (6), a closed secondary interior cavity (8).

A tire member of a non-pneumatic tire is provided. An inner circumference of the tire member is provided with a mounting protrusion. Securing notches for securing the tire member to a rim are provided at two sides of where the mounting protrusion joins the tire member. A position fixing groove is provided at an inner circumference of the mounting protrusion. The position fixing groove has an annular structure; alternatively, the position fixing groove has an arc structure, and a plurality of the position fixing grooves having the arc structure are uniformly distributed at the inner circumference of the mounting protrusion in a circumferential direction. Two side walls of the position fixing groove are provided with several securing holes below the securing notches, respectively. The securing holes pass through the side walls of the position fixing groove, and partially coincide with securing notches at an outer side.

A disclosed example embodiment of a gauge wheel tire includes a first polyurethane sidewall portion, a second polyurethane sidewall portion, a polyurethane ground-engaging portion, and a polyurethane axial support portion. The first polyurethane sidewall portion is spaced apart from the second polyurethane sidewall portion, and the polyurethane ground-engaging portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion and is adapted to contact a ground surface as the gauge wheel tire rotates about an axis of rotation. The polyurethane axial support portion extends from the first polyurethane sidewall portion to the second polyurethane sidewall portion, and is spaced apart from the polyurethane ground-engaging portion to form a gap that allows radial movement of the polyurethane ground-engaging portion relative to the polyurethane axial support portion.

A wheel structure includes a rim and a tire. The rim includes a body, hub and spokes. The body has two edges which first and second flanges are annularly disposed at, respectively, to form a tire holder. First and second walls are annularly disposed at the edges of the body in such a manner to face the first and second flanges, respectively, allowing a first engaging slot to be formed between the first flange and the first wall and a second engaging slot to be formed between the second flange and the second wall. The tire is coupled to the tire holder. First and second coupling portions are disposed at two inner edges of the tire and coupled to the first and second engaging slots, respectively. A hollow core portion is formed between the first and second coupling portions.

A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.

The disclosed technology generally relates to a tire and more particularly to a non-pneumatic tire. The non-pneumatic tire that has maneuverability similar to a pneumatic tire even without using air pressure, and can support the load of a vehicle and can guide performance-oriented tire deformation behavior by using a meta structure. In an aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that serves as a structural support between the rim and the tread, in which the spoke unit is formed in a meta structure in which unit structures are repeated.

Tire includes a casing with an interior, and the casing has an inside diameter. A fill is provided in the interior of the casing. The fill includes a first layer and a second layer adjacent to the first layer. The first layer has an outside diameter and an inside diameter, and the outside diameter is the same as the inside diameter of the casing for contacting the casing. The first layer has a face and open voids. The open voids of the first layer have a first volume and are open to the face. The second layer has an outside diameter that is the same as the inside diameter of the first layer. The second layer has a face and open voids, and the open voids of the second layer have a first volume and are open to the face.
