Therefore, the thickness of the whole glue layer 2 can be accurately controlled in the process of adhering the layer bodies 20.

In the specific implementation process, the plurality of layers 20 include a first layer 21, and the first layer 21 is attached to the tire body 1; the tire further includes: the rubber sheet 3 is arranged between the first layer body 21 and the tire body 1, and the rubber sheet 3 is respectively attached to the first layer body 21 and the tire body 1; the width L1 of the first layer 21 is larger than the width L2 of the rubber sheet 3, taking the axial direction of the carcass 1 as the width direction. First layer body 21 can be complete the cover on film 3 like this, has avoided the too big easy problem that takes place the turn-up of width of film 3, makes firm laminating of film 3 on matrix 1.

Further, the tire further comprises: a cloth pad 4 detachably connected with one side of the film 3 far away from the first layer body 21, wherein the width L3 of the cloth pad 4 is larger than the width L1 of the first layer body 21; wherein the range of L1-L2 is more than or equal to 10mm and more than or equal to L1-L2 and more than or equal to 5 mm. In the practical application process, with the width that cloth liner 4 is greater than the width of film 3, can keep the surface of film 3 fresh, between film 3 needs to laminate, tear cloth liner 4, the viscidity of the face of bonding of film 3 this moment is better.

As shown in fig. 2, each layer 20 includes a first end and a second end which are oppositely arranged from the crown of the tire to the bead of the tire; the plurality of layers 20 comprise a first layer 21 and a second layer 22 which are sequentially arranged, and the first layer 21 is attached to the tire body 1; the horizontal distance between the first end of the first layer 21 and the first end of the second layer 22 is S2. The plurality of layers 20 further include a third layer 23, and the third layer 23 is disposed on a side of the second layer 22 away from the first layer 21; the horizontal distance between the first end of the second layer 22 and the first end of the third layer 23 is S1; s1 is more than or equal to 30mm, and S2 is more than or equal to 30 mm. The horizontal distance between the first section of the first layer body 21 and the first end of the second layer body 22 is limited, and the horizontal distance between the first end of the second layer body 22 and the first end of the third layer body 23 is limited, so that the surface contour of the molding compound layer formed after the first layer body 21, the second layer body 22 and the third layer body 23 are completely attached is attached to the contour surface of the tire body 1, and the drop of the molding compound layer 2 in the radial direction of the tire body 1 is reduced.

In a particular application, the tire further comprises: and at least part of the seam allowance layer 5 is attached to one side of the molded rubber layer 2 far away from the tire body 1. The tire further includes: the side wall glue film 6 is attached to one side, far away from the tire body 1, of the molded glue layer 2, the side wall glue film 6 extends from the side wall of the tire to the bead direction of the tire, and one end, close to the bead, of the side wall glue film 6 is attached to the layer body of the molded glue layer 2. The rigidity of the tire is further improved by arranging the bead rubber layer 5 and the side rubber layer 6.

In another embodiment of the present invention, the layer body 20 has a first attaching end surface 201 and a second attaching end surface 202 which are oppositely disposed, a portion of the first attaching end surface 201 is attached to the carcass 1, the first attaching end surface 201 is a plane, and the second attaching end surface 202 is a curved surface. Specifically, by the both ends of layer body 20 to the middle part direction of layer body 20, the thickness of layer body 20 increases gradually, like this when laminating layer body 20, because the thickness at both ends is less, has avoided the easy stick up limit problem that insecure emergence of laminating at the tip of layer body 20.
