Abstract
This invention relates to a pneumatic rubber tire having a rubber sidewall composition of a lug and groove configuration which is designed to be ground contacting. Such sidewall configuration is of a rubber composition comprised of a blend of natural rubber and cis 1,4-polybutadiene rubber which contains specified carbon black reinforcement and silica together with a coupling agent. The tire tread rubber composition differs from the rubber composition of said sidewall lug and groove configuration by being exclusive of silica and coupling agent and carbon black reinforcement exclusive of said specified carbon black.
