PNEUMATIQUE A ADHERENCE SUR GLACE AMELIOREE

摘要

A tyre whereof the tread comprises a rubber composition based on at least one diene elastomer such as natural rubber and/or polybutadiene, more than 30 pce of a liquid plasticising agent, between 50 and 150 pce of a non-black reinforcing filler such as silica, optionally carbon black at a level lower than 3 pce, between 5 and 50 pce of a photocrosslinkable liquid polymer resin such as a poly(butadiene-acrylate) or poly(butadiene-methacrylate) resin, and between 5 and 70 pce of microparticles of poly(vinyl alcohol). Such a rubber composition greatly improves the grip of the tyre on cold ice.
