[Subject] To provide a pneumatic tire whose snow performance is improved without affecting its dry performance. [Measures for Addressing the Subject] Step portions 22 F and 22 R that are continuous so as to protrude respectively from step-in sides and kick-out sides of each of blocks 20 configuring a tread portion 16 are disposed in a pneumatic tire, and the step portions 22 are disposed in a staggered manner in the tread portion 16 . Thus, even when the step portions 22 are disposed, the rigidity of the blocks 20 does not decline that much and dry performance is not affected that much. Further, snow performance can be improved by the edge pressure of the step portions 22.
