TIRE USING RUBBER COMPOSITION CONTAINING MODIFIED POLYMER

摘要

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) (m 2 /g) and the mode A ac in diameters (nm) of primary aggregates determined by acoustic measurement of particle size distribution satisfy equation (A) shown below: A ac ‰§ - 0.76 × CTAB + 274
