A pneumatic tire obtained by using a rubber composition containing 100 parts by mass of a rubber component comprising at least one of natural rubber and diene base synthetic rubber, 20 to 150 parts by mass of precipitated silica as a filler in which a cetyltrimethylammonium bromide-adsorbing specific surface area (CTAB) (m 2 /g) and the mode A ac in diameters (nm) of primary aggregates determined by acoustic measurement of particle size distribution satisfy equation (A) shown below and in which a difference between an ignition loss (mass reduction % when heated at 750°C for 3 hours) and a heating loss (mass reduction % when heated at 105°C for 2 hours) satisfies equation (B) shown below and 1 to 25 parts by mass of at least one specific sulfur-containing silane compound as a silane coupling agent: A ac ‰§ - 0.76 × CTAB + 274 ignition loss - heating loss ‰¦ 3 |
