Title:
ゴム組成物及びそれを用いた空気入りタイヤ
Document Type and Number:
Japanese Patent JP5759118
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rubber composition which can fully compatibilize rolling resistance and wear resistance when applied to a tire member such as tread.SOLUTION: This rubber composition is obtained by formulating hydrated silica to a rubber component. In the hydrated silica, a specific relation between a cetyltrimethyl ammonium bromide adsorption specific surface area (CTAB)(m/g) and an ink bottle-like pore volume index (IB) is satisfied; and a specific relation between ignition loss (mass reduction on heating at 750°C for 3 hours)(mass%) and loss on heating (mass reduction on heating at 105°C for 2 hours)(mass%) is satisfied.
