The invention discloses a wrapped PU dual-density tire, which comprises an outer tire and a tire body, wherein the outer tire is greater than the tire body in density and wraps the tire body. According to the invention, the thickness of the outer tire can be adjusted as required instead of being fixed, and meanwhile, the tear resistance and the scratch resistance of the whole tire are improved, sothat the service life of the whole tire is prolonged; the overall supporting force of the tire is improved, and thus the loading capacity of the foamed tire is improved; and the deformation resistance of the tire is improved, and particularly, when the tire does not move under static pressure, the deformation amplitude is greatly reduced.

    一种包裹型PU双密度轮胎,包括外胎和胎体;外胎密度大于胎体密度,外胎包裹在胎体的外部。本发明中外胎的厚度可以根据需求来调节,而不是固定不变的,同时提高了轮胎整体的抗撕裂和抗刮擦性能,进而提高了轮胎整体寿命;提高了轮胎的整体支撑力,进而提高了发泡轮胎的载重能力;提高了轮胎抗变形能力,特别是轮胎在静压下不动时,变形幅度大幅下降。
