A toy car tire includes a tire main body and a filler core. The tire main body includes an inner cavity and a first opening. The inner cavity is surrounded and formed by a side wall of the tire main body, and the first opening is in communication with the inner cavity. The filler core is inserted into the inner cavity through the first opening. The filler core is configured for filling the inner cavity. Therefore, the filler core is capable of filling the inner cavity of the tire main body to support the tire main body, making the tire main body fuller and less prone to deformation. Moreover, compared with an inflatable tire, since the inner cavity is filled with the filler core, the toy car tire is not afraid of being punctured. Even if punctured, the tire main body of the tire is still full.
