Abstract
A tire prepared by using a rubber composition compounded with a modified conjugated diene base polymer obtained by reacting an active site of a conjugated diene base polymer with a hydrocarbyloxysilane compound which may have a functional group to introduce a functional group having high affinity with precipitated silica and precipitated silica in which a cetyltrimethylammonium bromide-adsorbing specific surface area (CTAB) (m2/g) and the mode Aac in diameters (nm) of primary aggregates determined by acoustic measurement of particle size distribution satisfy equation (A) shown below:Aac≧−0.76×(CTAB)+274 (A).
