Summary of the invention

The object of this invention is to provide and a kind ofly can improve comfort, reduce the solid tyre structure of tire weight simultaneously.

For achieving the above object, solution of the present invention is:

, this tire is rubber or PU material, it comprises the tyre surface of kiss the earth, coordinates the internal face of wheel hub and is positioned at tyre surface and the sidewall of internal face both sides; Wherein: on the internal face of this tire, be at least circumferentially uniformly distributed with the hole of a circle, each hole is to form in carcass from internal face, and the axle center in each hole and its tangent line at tire inner wall face perpendicular.

On the internal face of described tire, distribute two circles or the two above holes of circle, and hole of each circle is and is staggered.

Described hole for from internal face to the counterbore extending in carcass.

Described hole is cylindrical bore or polygon counterbore.

Described hole is for running through the through hole of formation to tyre surface from internal face.

Described hole is cylindrical hole or polygon through hole.

On described tyre surface, be coated with one deck rubbery cover tyre.

On described tyre surface and sidewall, be coated with one deck rubbery cover tyre.

On the inwall of described rubbery cover tyre, the position of corresponding aperture is provided with the projection that can be embedded in wherein.

Adopt after such scheme, because band tyre of the present invention is to form porosely from inner wall surface thereof, make band tyre carcass portion form hollow, can effectively alleviate tire weight; Another each hole is to be being distributed on tire radially, when tire used is stressed, to the application of force direction in each hole be just honeycomb structure be subject to force direction (axial direction in hole), therefore tire is difficult for producing distortion in the position in hole, though distortion, Kong Yihui traction periphery deform in same pace, jitter problem while there will not be tyre rotation, tire of the present invention is loaded onto after wheel hub simultaneously, and the hollow space in each hole of tire plays vacuum action, can effectively improve the traveling comfort of tire used.
