TIRE WITH OPTIMIZED APEX
摘要:
A pneumatic tire is described having a triangular shaped apex which extends radially outward of the bead core, and wherein the apex is formed of at least two zones. Each zone is formed of a different material, wherein the first zone extends from the base of the apex to the tip of the apex, and the second zone is located adjacent the ply. The zones are preferably formed by extrusion to form one cohesive apex. The first zone is formed of a material having a G″/G′ ratio in the range of about 0.155 to about 0.183. The second zone is formed of a material having a G″/G′ ratio in the range of about 0.125 to about 0.133.
