A wheel structure includes a rim and a tire. The rim includes a body, hub and spokes. The body has two edges which first and second flanges are annularly disposed at, respectively, to form a tire holder. First and second walls are annularly disposed at the edges of the body in such a manner to face the first and second flanges, respectively, allowing a first engaging slot to be formed between the first flange and the first wall and a second engaging slot to be formed between the second flange and the second wall. The tire is coupled to the tire holder. First and second coupling portions are disposed at two inner edges of the tire and coupled to the first and second engaging slots, respectively. A hollow core portion is formed between the first and second coupling portions.
