A non-pneumatic tire, comprising a polyurethane composite layer which comprises a polyurethane matrix material and a thermoplastic expandable polymer material dispersed in the polyurethane matrix material. The polyurethane matrix material is obtained by a reaction comprising the following components: (A1) a polyisocyanate composition; (B1) at least one polyalkylene oxide-based polyether polyol having a number average molecular weight of 2000-7000 g/mol, calculated according to GB/T 7383-2007: test method for hydroxyl value, and containing 15-35 wt % of solid particles based on the total weight of the polyether polyol; (B2) one or more chain extenders; (B3) one or more catalysts; and (B4) one or more foaming agents. Also provided herein is a method for preparing a non-pneumatic tire, a process for manufacture of a non-motor vehicle, and a non-motor vehicle.
