FIG5 is a graph showing a rolling resistance and a vibration displacement depending on a hardness of a core of a tire structure according to an example of the present disclosure  FIG5 is a graph showing a rolling resistance and a vibration displacement depending on a hardness of a core of a tire structure according to an example of the present disclosure
The rolling resistance and the vibration depending on the shore C hardness of the core were as shown in Table 4 and FIG5. FIG5 is a graph showing a rolling resistance and a vibration displacement depending on a hardness of a core of a tire structure according to an example of the present disclosure. To be specific, FIG5 is a graph of the rolling resistance and the vibration displacement at a speed of 20 km/h depending on the hardness of the core shown in Table 4. Referring to the results of Example 4 as shown in Table 4 and FIG5, it can be seen that the shore C hardness of the core 120 according to an embodiment of the present disclosure may be from 20 to 80 or less, but may not be limited thereto.  The rolling resistance and the vibration depending on the shore C hardness of the core were as shown in Table 4 and FIG5.

['1. A tire structure capable of being combined with a rim, comprising: an air tube; a core provided on the air tube; and a tire outer layer provided on the core, wherein the core includes a body part positioned above a transverse diameter of the air tube and a wing part positioned under the transverse diameter of the air tube, and a lower end of the wing part is placed under an upper surface of the rim.', '2. The tire structure of Claim 1, wherein when the air tube is inflated, a compression ratio of thickness for the body part of the core is from 10% to 50% or less.']
