A non-pneumatic tire comprises a radially inner ring for contacting a vehicle rim, a radially outer ring and a support structure including spokes extending from the radially outer ring to the radially inner ring. The spokes delimit openings in the support structure, which extend in a width direction of the non-pneumatic tire. The non-pneumatic tire has a reinforcement structure comprising loops of reinforcement cord, each loop extending around one of the openings. Each spoke has arranged therein radial reinforcement cord segments extending radially between the inner ring and the outer ring. The radial reinforcement cord segments are lined up parallel to one another along the width direction of the non-pneumatic tire.

A non-pneumatic tire 1 comprises: a radially inner ring 3 coupled with an tire wheel H; a radially outer ring 2 comprising a radially outermost annular tread portion 5 having electrical conductivity, and a radially innermost second portion 6; and radial link portions 4 connecting between the radially outer and inner rings 2 and 3. The second portion 6, radial link portions 4 and radially inner ring 3 are each formed of a resin material containing carbon black to have electrical conductivity. The resin material comprises 0.5 to 20 parts by mass of carbon black having a BET specific surface area of from 300 to 1500 sq.Math.m/g with respect to 100 parts by mass of its resin component. The tread portion 5 is electrically connected with the second portion 6.

A shear band and a non-pneumatic tire is described which includes a ground contacting annular tread portion; a shear band, and a connecting web positioned between a hub and the shear band. The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The three-dimensional spacer structure further includes a plurality of cells formed between the connecting members, and wherein one or more of the cells are filled with a filler material. The filler material may be foam or a thermoplastic elastomer.

The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The first and second layer of fabric of the three-dimensional spacer structure are reinforced with a respective first and second layer of non-crimped fabric, eliminating the need for a rubber shear layer and reinforcement layers commonly used for the shear band.

Provided is an non-pneumatic tire that includes thermoplastic elastomer which is pre-tensioned during the process of forming the non-pneumatic tire. The pre-tension is provided by a thermal means that is naturally available in the forming process. This results in an efficient manufacturing combined with efficiency of pre-tension, without a complexity of adding a pre-tension from mechanical means.

A non-pneumatic tire (100) having an annular beam (200) and an annular support (103) comprising a plurality of thermoplastic elastomeric spokes formed by a thermoplastic injection process. When manufacturing this non-pneumatic tire via a mold, then the radial extent of a mold cavity is defined by the radially inner extent of the annular beam (200). The non-pneumatic tire's annular beam (200) includes a first elastomer and a circumferential reinforcement extended in a circumferential direction. The annular beam (200) is free of the circumferential reinforcement at an axial extent over a width of at least 8 mm the axial extent comprising the first elastomer. The plurality of thermoplastic elastomeric spokes are made of a second elastomer and extend radially inward from the annular beam (200). The present invention also refers to a process for forming such a non-pneumatic tire (100).
