TIRE EQUIPEMENT WHERE THE TIRE TREAD COMPRISES A THERMO-EXPANSIBLE RUBBER |
摘要 |
<p>A tyre is formed of a tread that includes, in the unvulcanized state, a heat-expandable rubber composition. The rubber composition includes at least a diene elastomer, 70 to 120 phr of a reinforcing filler, between 5 and 25 phr of a blowing agent, and between 5 and 25 phr of a thermofusible compound. The melting point of the thermofusible compound is between 70° C. and 150° C. and the total amount of the blowing agent and the thermofusible compound is greater than 15 phr. The rubber composition provides improved grip for the tread on melting ice.</p> |
