The sealant layer may also include a second sealant layer formed by a second sealant string adjacent to at least a portion of the first sealant layer. The second sealant layer may be equal to or smaller, in width, than the first sealant layer in an axial direction of the pneumatic tire. The sound absorbing material may be smaller in width than the first sealant layer in the axial direction.
