Abstract: A 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.

Abstract: A tire member of a non-pneumatic tire is provided. An inner circumference of the tire member is provided with a mounting protrusion. Securing notches for securing the tire member to a rim are provided at two sides of where the mounting protrusion joins the tire member. A position fixing groove is provided at an inner circumference of the mounting protrusion. The position fixing groove has an annular structure; alternatively, the position fixing groove has an arc structure, and a plurality of the position fixing grooves having the arc structure are uniformly distributed at the inner circumference of the mounting protrusion in a circumferential direction. Two side walls of the position fixing groove are provided with several securing holes below the securing notches, respectively. The securing holes pass through the side walls of the position fixing groove, and partially coincide with securing notches at an outer side.
