Abstract
Disclosed herein are embodiments of a tread block structure of a pneumatic tire including at least one tread cone having different physical properties from the outer surface toward the inner surface. According to various exemplary embodiments of the present invention, the tread cones with different properties existing in the tread block may control the rigidity of the tread block without the trade-off on other tread performance, and thus the tread block structure and a pneumatic tire comprising the same exhibit an improved balance between traction, cornering performance, and abrasion resistance.
