MATERIAL FORMULA FOR PNEUMATIC TYRES FOR CIVIL ENGINEERING EQUIPMENT

摘要

1. A tread for a pneumatic tire for civil engineering equipment, having a base of a butadiene-styrene copolymer elastomer reinforced by carbon black and optionally comprising an extension oil, characterized by the fact that the elastomer has a styrene content of between 35 % and 55 % by weight per 100 parts by weight of elastomer and that the ratio of parts by weight of carbon black to the parts by weight of elastomer or elastomer plus extension oil being from 0.6 to 0.65.
