Provided are a pneumatic tire, a method of producing the pneumatic tire, and a tire curing mold, with which decrease in wet performance of a pneumatic tire in a worn state can be effectively prevented while chipping of land portions such as blocks is prevented in releasing the tire from a mold. The pneumatic tire of the present invention includes: a tread portion provided with groove portions and land portions; and sipes provided in the land portions. Each of the sipes has at least one end, in a longitudinal direction, being terminated within the corresponding land portion. Each sipe is provided with: a first offset portion protruding toward one side in a sipe thickness direction; and a second offset portion protruding toward the other side in the sipe thickness direction at a position on an inner side, in a tire radial direction, of a position at which the first offset portion protrudes. For each sipe, a sipe length (L) in a worn state is set to be substantially the same as a sipe length (L) in an original state, and a sipe path length (M) in the worn state is set to be larger than a sipe path length (M) in the original state. The method of producing a pneumatic tire of the present invention and the tire curing mold are used for producing the pneumatic tire.
