To provide a pneumatic tire having a sealant agent layer which has self-sealing characteristics and supports improved riding comfort and improved handling characteristics.SOLUTION: A pneumatic tire comprising a tread portion 10 having circumferential grooves 9 and circumferential ribs 8 or rows of tread blocks; an inner surface defining a tire cavity 6; and a sealant agent layer 5 at least partially covering the inner surface radially below the tread portion 10 within the tire cavity 6. The sealant agent layer 5 comprises raised portions 19 of a sealant agent, where the raised portion 19 of the sealant agent is provided radially below each of at least two of the circumferential grooves 9, and where the sealant agent layer 5 has larger radial thickness in the raised portions 19 than that in areas 18 radially below the circumferential ribs 8 or the rows of the tread blocks.SELECTED DRAWING: Figure 2
