TIRE USING RUBBER COMPOSITION CONTAINING MODIFIED POLYMER

摘要

Disclosed is a tire using a rubber composition.  The rubber composition comprises a modified conjugated diene polymer containing a functional group, which has high affinity for hydrous silicic acid and has been introduced by reacting an active site in a conjugated diene polymer with a hydrocarbyloxysilane compound optionally having a functional group, and hydrous silicic acid having a cetyl trimethylammonium bromide adsorption specific surface area (CTAB) (m2/g) and a primary aggregate diameter mode Aac (nm) determined by acoustic particle size distribution measurement that satisfy formula (A). Aac = -0.76 × (CTAB) + 274 ??? (A)
