Rubber composition with high processability for run-flat tire

摘要

The crosslinkable rubber composition comprises a first elastomer consisting of polybutadiene having a Mooney plasticity ranging from 40 to 70 Mooney units, the content of the first elastomer being strictly greater than 50 phr, a second elastomer, and a carbon black having a specific surface area within a range of values extending from 15 m²/g to 25 m²/g and an oil adsorption number of compressed sample (COAN) within a range of values extending from 65 ml/100 g to 85 ml/100 g.
