Abstract:
The present invention provides a pneumatic tire including a sealant layer that has excellent tear resistance despite its being formed of a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire. Included is a pneumatic tire including an innerliner and a sealant layer located radially inside the innerliner, the sealant layer including a first sealant layer and a second sealant layer stacked in that order from the innerliner, the first sealant layer including a generally string-shaped sealant provided continuously and spirally along an inner periphery of the tire, the second sealant layer including a generally string-shaped sealant provided continuously and spirally along the first sealant layer, the sealant of the first sealant layer and the sealant of the second sealant layer extending in directions crossing each other.
