PNEUMATIC TIRE

In the pneumatic tire including a sealant layer containing an adhesive sealant on an inner surface of a tread portion, when a thickness of the sealant layer at 0° C. is G, a thickness of the sealant layer at 50° C. is G, a width of the sealant layer at 0° C. is W, and a width of the sealant layer at 50° C. is W, a rate of change Rof thickness expressed by R=(|G−G|/G)×100 is set to 3% or less, and a rate of change Rof width expressed by R=(|W−W|/W)×100 is set to 3% or less.
