The manufacture of tyres for motor vehicles adopts the technology radial carcass metal. It is clear that more stronger is adhesion of rubber to steel, more robust is the body of the tyre, which will be less sensitive to shock, chipping and bursts. The best metal salts are the cobalt ones that act on the reaction without depressing the rate of vulcanization of rubber. Less rate of vulcanization is observed using salts of other metals.
