[0007] Preferably, the outer surface of the tire body is provided with grooves, and a plurality of groups are provided.

[0008] In the above technical scheme, the grooves can improve the friction and grip between the tire body and the ground, so as to avoid slipping.

[0009] Preferably, the thickness of the aramid fiber layer is 1-3mm.

[0010] In the technical scheme, the aramid fiber layer has certain softness, high strength and toughness, and can resist deformation when subjected to a puncture force, and can disperse the puncture force to a larger area through interaction between the fibers, thereby effectively preventing puncture.

[0011] Preferably, the thickness of the polyester fiber layer is 2-5mm.

[0012] In the technical scheme, the polyester fiber layer can effectively improve the tear resistance of the tire, and can prevent cracks from expanding and prevent the tire from being broken under high load or in harsh road conditions when the tire encounters sharp objects or local stress concentration in complex road conditions such as potholed road surface during driving.

[0013] Preferably, the thickness of the fabric reinforcing layer is 2-4mm.

[0014] In the technical scheme, the fabric reinforcing layer is composed of fabric and rubber, the fabric has high strength and toughness, and the overall material is soft, and the rubber ensures soft touch. At the same time, due to the reinforcing effect of the fabric, the material is not easy to break when subjected to external forces such as stretching and tearing

[0015] Preferably, the metal ring and the arc-shaped ring are each composed of three layers of aluminum alloy thin plates, and the thickness of each layer of aluminum alloy thin plate is 0.05-0.08mm.

[0016] In the technical scheme, the metal ring can physically block the sharp object to prevent the tire from being penetrated by the sharp object, and the arc-shaped ring can protect the sidewall of the tire body.

[0017] Compared with the prior art, the anti-penetration tire has the advantages that:

[0018] (1) The aramid fiber layer is provided, the aramid fiber layer has certain softness, high strength and toughness, and can resist deformation when subjected to a puncture force, and can disperse the puncture force to a larger area through interaction between the fibers, thereby effectively preventing puncture, and the metal ring composed of three layers of aluminum alloy thin plates arranged on the inner wall of the tire body can further prevent the tire body from being penetrated by the sharp object, can effectively disperse the puncture force, and due to the light weight of the aluminum alloy thin plate, the weight of the tire body is not increased too much, which helps to improve the stability of the tire during driving.
