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.

A non-pneumatic tire is disclosed herein. The non-pneumatic tire includes a cylindrical tread configured to come into contact with a road surface, an aluminum wheel configured to form a circumference smaller than that of the tread and concentrically disposed inside the tread, and a polyurethane spoke configured to perform a shock absorbing action while connecting the tread with the aluminum wheel. The aluminum wheel includes a plurality of depressed grooves formed at predetermined intervals along the circumferential surface of the aluminum wheel. A plurality of vibration isolators made of vibration isolation material is inserted into the grooves.

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.
