<p>The purpose of the present invention is to provide a tire which has good processability, high fuel-efficiency, high wearing resistance and high fracture resistance. To achieve this purpose, disclosed is a rubber composition to be used as a tire member which comprises a denatured natural rubber having a polar group in a natural rubber molecule and hydrous silicic acid, wherein, in the hydrous silicic acid, a cetyl trimethylammonium bromide adsorption specific surface area (CTAB) (m2/g) and a primary aggregate diameter mode (Aac) (nm), which is determined by the acoustic particle diameter distribution measurement, satisfy formula: Aac=-0.76×(CTAB)+274.</p> |
