摘要

Tire with side composed of emulsu00e7o rubber of styrene / butadiene CIS 1,4 - polyisoprene rubber and cis - 1,4 - polybutadiene rubber.This invention relates to a tire with a composition that includes side rubber CIS 1,4 - polilsopreno, particularly a natural rubber, CIS 1,4 - polilsopreno, and high cis - 1,4 - polybutadiene rubber combined with a partial replacement of the rubber of the CIS 1,4 - poliiso Preno, particularly natural rubber.A styrene / butadiene rubber specialized (E-SBR) polymerized in emulsion, with a vitreous transition temperature (TG), similar to that of natural rubber, CIS 1,4 - polyisoprene, - 70 - 600C, and a styrene content limited connected at a range of 12 to 16%.
