More Information
Summary:The inventive tyre running thread comprises a rubber composition based on at least one type of diene elastomer, a non-black reinforcement filler, in particular inorganic, a coupling agent for bonding said dien elastomer and the filler, wherein said composition is characterised in that it also comprises a pro-photo oxidant agent and optionally a carbon black at a rate of less than 5 pce (parts by weight per hundred parts of elastomer). Said pro-photo oxidant agent is mainly embodied in the form of a radical or cationic photoinitiator activated or not by the presence of a photo-sensitiser. Tyres provided with said photo oxide (exposed to UV-visible radiation) running thread exhibit a substentially increased adherence on a wet road.
