PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of suppressing a crack growing toward the center of a land part from a sipe. SOLUTION: A pneumatic tire 1 includes a second rib, a shoulder rib and a center rib formed of an inside main groove and outside main groove in a tread part, and a multi sipe 10 and a crack guard sipe 11 in each rib (land part), wherein the crack guard sipe 11 is formed so as to surround an end (sipe most center side end 1A) on the most center line CL side of the multi sipe 10. In this way, the crack can be suppressed which is generated from the ends (sipe most center side end 1A) on the most center line CL side of the multi sipe 10 and grown toward a tire width direction.
