The present disclosure relates to the technical field of tires, and in particular to a non-pneumatic vacuum tire. The non-pneumatic vacuum tire includes a tread layer, a carcass ply layer and a puncture-resistant airtight layer. The tread layer is provided on the carcass ply layer and located at a crown; a pattern groove is formed in a surface of the tread layer; the puncture-resistant airtight layer is fixedly provided between the tread layer and the carcass ply layer or fixedly provided under the carcass ply layer; the puncture-resistant airtight layer includes one or more layers of canvas; a warp and a weft of the canvas each are formed by a plurality of filaments; and the canvas forms the puncture-resistant airtight layer by rubber impregnation and rubber coating; the puncture-resistant airtight layer at least covers a clinch to a shoulder; and a lower end of the puncture-resistant airtight layer extends to the clinch and forms a turn-up structure. Through the puncture-resistant airtight layer composed of the rubber impregnated and coated canvas, the vacuum tire achieves better puncture resistance and airtightness.
