A pneumatic tire which uses for a tire member a rubber composition comprising a rubber component comprising at least one selected from natural rubber and diene base synthetic rubber, silica having a nitrogen adsorption specific surface area (N2SA) of 210 to 260 m2/g and a dibutyl phthalate oil absorption (DBP) of 200 to 260 ml/100 g and at least one compound selected from aromatic polycarboxylic acid derivatives represented by the following Formula (I), wherein the blending amount of the above aromatic polycarboxylic acid derivatives is 0.5 to 4.0 parts by weight per 100 parts by weight of the rubber component, and carbon black added to the rubber composition has preferably a specific colloidal characteristic:
[(wherein R1 : a C1 ∼ C24 alkyl group, a C2 ∼ C24 alkenyl group, a C3 ∼ C24 aryl group or a halogen-substituted group thereof; R2 : H, OH, a C1 ∼ C24 alkyl group, a C1 ∼ C24 alkenyl group, a C3 ∼ C24 aryl group or a halogen-substituted group thereof; m, n = 1 ∼ 3; p = 0 ∼ 4; m + n + p = 6; X : -O-, -NR3- (R3 : H, a C1 ∼ C24 alkyl group), -O(R4O)-q (R4 : a C1 ∼ C4 alkylene group, and q = 1 to 5)].
