STUDDABLE TIRE

Stud holes (9) are formed in land portions defined by circumferential grooves extending in a tire circumferential direction and lug grooves extending in a direction intersecting the circumferential grooves provided in a tire tread of a studdable tire, first and second grooves (12, 13) having both ends thereof terminating within the land portion are disposed on a kick-out side of a region (R) enclosed by two circles (C1, C2) of different radii each having a center concentrical to a center of the stud hole (9) on the land surface, and a third land portion including intra-land grooves (14a) having both ends thereof terminating within the land portion and communicating grooves (14b) communicating the intra-land grooves (14a) with lug grooves, is disposed on a step-in side of the region (R), so as to inhibit ice powder occurring during vehicular travel on an ICE road surface from adhering to the spike pins, whereby, the steering stability performance of the studdable tire can be enhanced.
