Abstract
A formulation for a tire comprising natural rubber and synthetic rubber, a silane coupling agent and a lubricant. The tire tread formulation may further comprise a curing agent, a plasticizer, a cross-linking agent, an accelerator system, a pre-vulcanization inhibitor and a bio-waste material, such as calcium oxide which may be obtained from egg shells, is also provided.
