The tread compound consists of natural rubber , silica and canola oil. Mediator ingredient Cryo-Silan improves the compounds functionality under differing winterconditions. With this compound we achieve excellent winter- and wetgrip as well as wear resistance. Canola oil improves the tyres tear strength, ice- and snowgrip. Due to the high silica-amount the rolling resistance is very low, so that fuel-consumption and pollutant emissions are reduced.
