An airless tire includes a tread ring, a hub formed on radial direction inner side of the ring to be fixed to an axle, and a spoke structure connecting the ring and hub. The ring includes a tread rubber layer, a first reinforcing cord layer, a second reinforcing cord layer and a shear rubber layer between the first and second cord layers, the first and second cord layers and shear layer are formed such that ratio Eb.sub.1/Ee between tire circumferential direction tensile modulus Eb.sub.1 of the first cord layer and shear modulus Ee of the shear layer is 100 or greater and that ratio Eb.sub.2/Ee between tire circumferential direction tensile modulus Eb.sub.2 of the second cord layer and shear modulus Ee is 100 or greater, and each cord layer has a topping rubber having loss tangent tan b of 0.03 to 0.10 and tensile modulus E*b of 4 to 20 MPa.

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 tire for a vehicle has a structure in which a plurality of air blocks are detachably mounted in a circumferential direction of the tire. The tire is similar to an airless tire, in which a plurality of spokes are connected to and arranged between a tread rim part configured to come into contact with a road surface and a hub which is mounted to the wheel, and the tire is also similar to a pneumatic tire, in which an air block is replaceably inserted and mounted into an air block mounting space formed between the spokes.

A non-pneumatic tire comprising a pair of annular inner rim beads disposed parallel to each other and defining a cylinder, wherein the rim beads define the opposing ends of the cylinder, wherein the cylinder has an axis of rotation coincident with an axis of rotation of the tire wherein outer and inner are relative to the axis of rotation of the tire, where inner is closer to the axis of rotation and outer is further away from the axis of rotation; an annular outer layer oriented concentric with the circumference of the cylinder and comprising an outermost tread surface, the tread surface comprising tread rubber and tire carcass; a plurality of spaced apart support units, each support unit including: top and bottom members; a plurality of flexible curved support members extending between the top member and bottom member.

A toy car tire includes a tire main body and a filler core. The tire main body includes an inner cavity and a first opening. The inner cavity is surrounded and formed by a side wall of the tire main body, and the first opening is in communication with the inner cavity. The filler core is inserted into the inner cavity through the first opening. The filler core is configured for filling the inner cavity. Therefore, the filler core is capable of filling the inner cavity of the tire main body to support the tire main body, making the tire main body fuller and less prone to deformation. Moreover, compared with an inflatable tire, since the inner cavity is filled with the filler core, the toy car tire is not afraid of being punctured. Even if punctured, the tire main body of the tire is still full.
