[0008] The second holes and the third holes are symmetrically arranged.

[0009] The second holes and the third holes are communicated.

[0010] The first holes, the second holes and the third holes are communicated.

[0011] The depth of the first holes is less than the thickness of the rubber tire body in the radial direction.

[0012] The outer diameter of the rubber tire body is 480mm, and the width is 120mm; the outer diameter of the PU outer tire is 560mm, and the width is 160mm.

[0013] The rubber tire body is a new tire product or a recycled old rubber tire after polishing.

[0014] The tire tread of the PU outer tire is provided with a pattern.

[0015] Adopt above scheme, the utility model discloses a PU outer tire is embedded outside rubber tire body, improves the wear resistance of tire whole through PU outer tire, prolongs the service life of tire.And the utility model discloses a hole is set up on rubber tire body, makes PU outer tire and rubber tire body combine more stably, also effectively guarantees the service performance of tire.

[0025] As Figures 1-3 The utility model discloses a wear -resisting tire, it includes rubber tire body 10 and PU outer tire 20, wherein, the tread 11 of rubber tire body 10 is equipped with multiple radial setting's holes, and at least one sidewall 12 of rubber tire body 10 is equipped with multiple axial setting's holes, and PU outer tire 20 is formed in rubber tire body 10 outside and partially embedded in the hole of rubber tire body 10 by secondary injection molding.PU outer tire 20 covers in the tread 11 and sidewall 12 of rubber tire body 10, and is equipped with the line on the tread of PU outer tire 20.

[0026] The utility model discloses a PU outer tire 20 is embedded outside rubber tire body 10, improves the wear resistance of tire whole through PU outer tire 20, prolongs the service life of tire.And the utility model discloses a hole is set up on rubber tire body 10, makes PU outer tire 20 and rubber tire body 10 combine more stably, also effectively guarantees the service performance of tire.

[0027] AsFigure 4 and 5 As shown in the figure, in order to further improve the binding strength of the rubber carcass 10 and the PU outer tire 20, the embodiment is provided with a plurality of holes in each of the two sidewalls 12 of the rubber carcass 10, that is, a plurality of axially arranged second holes 121 are provided in one sidewall 12 of the rubber carcass 10, and all the second holes 121 are located on the same circumference; a plurality of axially arranged third holes 131 are provided in the other sidewall 12 of the rubber carcass 10, and all the third holes 131 are located on the same circumference. Further, the second holes 121 and the third holes 131 are symmetrically arranged, and the second holes 121 and the third holes 131 are communicated. The holes in the tread 11 of the rubber carcass 10 are first holes 111, which are communicated with the second holes 121 and the third holes 131. The depth of the first holes 111 is smaller than the thickness of the rubber carcass 10 in the radial direction. Of course, as shown in the figure, the first holes 111, the second holes 121 and the third holes 131 can also not be communicated with each other. Figure 6 As shown in the figure, the first holes 111, the second holes 121 and the third holes 131 can also not be communicated with each other.

[0028] In the utility model, the outer diameter D1 of the rubber carcass 10 is 480mm, and the width K1 is 120mm; the outer diameter D2 of the PU outer tire 20 is 560mm, and the width K2 is 160mm. In the utility model, the rubber carcass 10 can adopt a new tire product that has not been used, or a recycled old rubber tire. When a new tire product is used, the outer diameter of the new tire product is 480mm, and the width is 120mm; when a recycled old rubber tire is used, the old rubber tire needs to be polished to make the outer diameter 480mm and the width 120mm.

[0029] In summary, the key of the utility model lies in that the utility model embeds the PU outer tire 20 outside the rubber carcass 10, and improves the wear resistance of the whole tire through the PU outer tire 20, and prolongs the service life of the tire. And the utility model sets holes on the rubber carcass 10, so that the combination of the PU outer tire 20 and the rubber carcass 10 is more stable, and the use performance of the tire is also effectively guaranteed.
