[0014] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0015] Embodiment 1

[0016] Referring to Figure 1 and Figure 2 as shown, an EVA tire involved in this embodiment includes an inner ring 1 and an outer ring 2 arranged coaxially. A buffer belt 3 that bends and extends along a circular trajectory is provided between the outer ring 2 and the inner ring 1. The buffer belt 3 is connected end to end. A plurality of outer connecting protrusions 31 with equal adjacent interval angles are formed on the buffer belt 3. The outer connecting protrusions 31 are connected to the outer ring 2.
