Abstract
A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and an amino ether alcohol of formula (I): R1—O(—R2—O)n—R3—NH2 (I), in which R1 represents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, R2 and R3 independently represent a linear or branched alkylene group comprising from 1 to 18 carbon atoms, and n represents an integer from 0 to 20, it being understood that the amino ether alcohol bears one or more hydroxyl groups on at least one carbon-based chain chosen from R1, R2 and R3. The rubber composition is essentially devoid of guanidine derivative.
