A1
Abstract:
Provided is a pneumatic tire which can exhibit satisfactory sealing properties regardless of temperature conditions. The pneumatic tire includes a sealant layer 10 provided to the inner surface of a tread 1, the sealant layer 10 being constituted of a pressure-sensitive adhesive sealant. When the thickness of the sealant layer 10 at 0°C and that at 50°C are expressed respectively by G0 and G50 and the width of the sealant layer 10 at 0°C and that at 50°C are expressed respectively by W0 and W50, then the thickness change RG shown by equation (1) is regulated to 3% or less and the width change RW shown by equation (2) is set at 3% or less. Equation (1): ＲG=(|Ｇ50-Ｇ0|/Ｇ0)×100 Equation (2): ＲW=(| W50-Ｗ0| /Ｗ0)×100
