[0025] I-Definition

[0026] Within the meaning of the present invention, the expression "parts by weight per hundred parts by weight of elastomer" or (phr) is understood to mean parts by weight per hundred parts by weight of elastomer, whether thermoplastic or non-thermoplastic. In other words, thermoplastic elastomers are elastomers.

[0027] In this document, all percentages (%) shown are percentages (%) by weight unless expressly stated otherwise.

[0028] Furthermore, any numerical range indicated by the expression "between a and b" represents a numerical range extending from greater than a to less than b (i.e. excluding the limits a and b), while any numerical range indicated by the expression "a to b" Ranges are intended to mean a range of values ​​extending from a up to b (ie including the strict limits of a and b). In this document, when a numerical range is indicated by the expression "a to b", the range indicated by the expression "between a and b" is also prefer...

Abstract

The invention relates to a tire having a sidewall comprising a composition comprising at least an elastomeric matrix comprising at least one diene elastomer and a thermoplastic elastomer, the diene elastomer selected from butadiene polymers having a glass transition temperature less than or equal to -50°C, said thermoplastic elastomer comprising at least one elastomeric block and at least one thermoplastic block and not comprising polyisobutylene blocks; liquid plasticizers, The liquid plasticizer has a glass transition temperature of less than -70°C; a crosslinking system; and a reinforcing filler.

Description

technical field [0001] The present invention relates to tyres, and more particularly to the tyre's sidewall, that is to say, by definition, to the layer of elastomer located radially on the outside of the tyre, and in contact with the ambient air. Background technique [0002] Three types of regions can be defined within a tire: [0003] - the radially outer region in contact with ambient air, which substantially consists of the tread and the outer sidewall of the tyre. The sidewall is the layer of elastomer located outside the carcass reinforcement with respect to the inner cavity of the tyre, between the crown and the beads so as to completely or partially cover the area of ​​the carcass reinforcement extending from the crown to the beads. [0004] - The radially inner region in contact with the inflation gas, which generally consists of a layer (sometimes called an inner liner) that is gas-tight with respect to the inflation gas. [0005] - The inner region of the tyre,...
