Abstract
PURPOSE: The titled rubber composition giving a tire with little rolling resistance and excellent durability, obtd. by the incorporation of a polybutadiene rubber having a specified or larger amt. of a vinyl component, a natural rubber and isoprene rubber as a rubber base.
CONSTITUTION: The target rubber composition for bead apex of a radial tire is prepd. by incorporating as a rubber base a rubber consisting of 20W100pts.wt. polybutadiene rubber obtd. by the soln. polymn., etc. of butadiene in a hydrocarbon solvent in the presence of a catalyst such as methyllithium or triethylaluminum, and containing at least 40wt% vinyl component and 80W0pts.wt. natural rubber, isoprene rubber or a mixture thereof, each based on 100pts.wt. total rubber component. Using the rubber as bead apex for a radial tire keeps energy loss in the apex to a minimum.
