PROBLEM TO BE SOLVED: To provide a tire using a rubber composition in which dispersion of silica is good and which is suitable for a tread rubber member improved in both wear resistance and low heat generating property and also having enhanced workability. SOLUTION: The tire uses in a tire member a rubber composition prepared by blending a natural rubber in which a non-rubber component has been degraded and hydrous silicic acid, wherein a cetyltrimethylammonium bromide adsorption specific surface area (CTAB) (m<SP>2</SP>/g) of the hydrous silicic acid and a mode A<SB>ac</SB>(nm) of the diameters of primary aggregates obtained by acoustic particle size distribution measurement satisfy the expression: A<SB>ac</SB>≥-0.76×(CTAB)+274.
