A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and a primary amine of formula (I): R&#x2014;NH(I), in which R represents a linear or branched hydrocarbon group comprising from 8 to 24 carbon atoms. The rubber composition is essentially devoid of guanidine derivative.

Tire comprising a composition essentially free of guanidine derivative and comprising a primary amine

The invention relates to a tire rubber composition based on at least one diene elastomer, an inorganic filler as reinforcing filler, a coupling agent providing the bonding between the inorganic filler and the diene elastomer, characterized in that the coupling agent is an azosilane compound of following formula (I):(G)(G)Si&#x2014;Z&#x2014;NH&#x2014;C(O)&#x2014;N&#x2550;N&#x2014;C(O)&#x2014;NH&#x2014;Z&#x2014;Si(G)(G)&#x2003;&#x2003;(I)in which:

Rubber tire composition comprising an azo-silane coupling agent

A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and a hydroxyalkylpiperazine of formula (I): in which Rrepresents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, Rrepresents a linear or branched alkylene group comprising from 1 to 18 carbon atoms, it being understood that Rand Rcan bear one or more additional hydroxyl groups. The rubber composition is essentially devoid of guanidine derivative.

Tire comprising a composition essentially free of guanidine derivative and comprising a hydroxyalkylpiperazine

A tire comprising a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and an alkali metal hydroxide or alkaline earth metal hydroxide. The rubber composition is essentially devoid of guanidine derivative.

Tire comprising a composition essentially free of guanidine derivative and comprising an alkali metal hydroxide or alkaline-earth metal hydroxide

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): R&#x2014;O(&#x2014;R&#x2014;O)&#x2014;R&#x2014;NH(I), in which Rrepresents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, Rand Rindependently 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 R, Rand R. The rubber composition is essentially devoid of guanidine derivative.
