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).
