摘要： The tire (10B) comprises a tread (12) including a running layer (14) which is intended to come into contact with the ground when the tire (10B) rolls on the ground, and a sublayer (16) located radially inwards from the running layer (14). The tread (12) comprises at least one fluid passage (22) between the sublayer (16) and the air surrounding the tire (10B). The sublayer (16) comprises a cellular material. The fluid passage (22) comprises an element chosen from a groove (20) and a cut (26), formed in the running layer (14) and extended by at least one well (28) acting as a radial extension of the element, formed between the groove (20) and/or the cut (26) and the sublayer (16). Each well (28) forms a localized part of the fluid passage (22).

摘要： A self-sealing elastomer composition that can be used especially as a puncture-resistant layer in an inflatable article, comprising: as predominant elastomer, an unsaturated diene elastomer; a thermoplastic hydrocarbon plasticizer resin with a weight content of between 30 and 90 phr; a liquid plasticizer, the Tg (glass transition temperature) of which is below −20° C., with a weight content between 0 and 60 phr; and 0 to less than 30 phr of a filler. Also disclosed is an article such as a tire provided with the puncture-resistant layer comprising the self-sealing elastomer composition. The puncture-resistant layer is advantageously combined with an airtight layer, for example based on butyl rubber, so as to form, in the inflatable article, a puncture-resistant airtight laminate.

摘要： A tire tread includes a plurality of elements in relief (rib and/or block) having lateral faces, and a contact face intended to come into contact with the roadway during travel. The intersection of each lateral face with the contact face forms a ridge. The tread also includes a plurality of cutouts each defined by opposing main faces. Each tread pattern element is formed with at least one base mix. As viewed in section in a plane containing the thickness of this tread, at least one face defining at least one cutout is formed at least in part with a covering mix. The base mix exhibits a gripping action on wet ground which is lower than a gripping action of the covering mix on the same ground.
