This invention discloses a hollow EVA foam tire structure capable of carrying heavy loads, particularly a hollow EVA form tire having an accommodating space between the inboard sides of the tire. The tire is comprised of a plurality of sections substantially arranged into an annular shape, and a wheel core being hollow on both sides, such that a plurality of protruded block sections is disposed on the internal side of the flange section extended from the accommodating space and both sides of the tire are covered by a rim having two corresponding external flange surfaces at the external sides, and a pointed splinter is disposed on the internal side of the external flange surface and a protruded block section is protruded from the surrounding surface of the flange end at the internal side of the rim, so that the protruded block sections of the wheel core are alternatively and mutually engaged. Therefore, when the two corresponding rims are securely coupled, the pointed splinters of the rim can be pierced and fixed into the tire, and the internal side of the tire is embedded into the hollow section of the wheel core by the compressed force. Therefore, the tire, the wheel core and the two side rims can be coupled more securely so as to enhance the carrying capacity of the tire by the wheel core.
