PNEUMATIC TIRE WITH TREAD

摘要

The present invention is directed to a pneumatic tire comprising a ground contacting tread, the tread comprising a rubber composition comprising from about 60 to about 90 phr of a functionalized solution polymerized styrene-butadiene rubber having a bound styrene content of at least 36 percent by weight, a vinyl 1,2 content of less than 25 percent by weight, and functionalized with an alkoxysilane group and a thiol group; from about 40 to about 10 phr of a high-cis polybutadiene; and from about 50 to about 150 phr of silica.
