TYRE

A tire whose tread consists totally or partly of a rubber composition which comprises at least 80 phr of a copolymer of ethylene and of a 1,3-diene which contains at least 70 mol % of ethylene units, between 25 phr and 55 phr of a carbon black, less than 1 phr of sulfur and a vulcanization accelerat...

Beschreibung
Zusammenfassung:	A tire whose tread consists totally or partly of a rubber composition which comprises at least 80 phr of a copolymer of ethylene and of a 1,3-diene which contains at least 70 mol % of ethylene units, between 25 phr and 55 phr of a carbon black, less than 1 phr of sulfur and a vulcanization accelerator is provided. The carbon black representing more than 60% by mass of the reinforcing filler of the rubber composition, the mass ratio between the sulfur content and the amount of vulcanization accelerator in the rubber composition being less than 1. The vulcanization accelerator is a primary accelerator or a mixture of a primary accelerator and of a secondary accelerator. Such a composition has good cohesion properties.
