Embodiment Construction

[0036] figure 1 A cross-sectional view of an example tire comprising sidewalls 2 and a crown region 3 provided with a tread 4 is schematically shown. As shown, the tire is provided with a reinforcing structure 5 extending from one sidewall to the other and passing through the crown region 3 .

[0037] The insert 6 is arranged on at least one sidewall and bears against the axially outer part of the reinforcing structure 5 .

[0038] This insert consists of a first elastomeric composition serving as a matrix, within which a second elastomeric composition originating from recycled tires is substantially homogeneously distributed.

[0039] The proportion of the second elastomer composition is greater than or equal to 40%, more preferably greater than 60%.

[0040] The particle size distribution of the second elastomeric composition is such that the average diameter of the individual particles is less than 1 mm, preferably less than 0.5 mm, even more preferably less than 0.2 mm....

Abstract

A tire (1) comprising sidewalls (2), a crown zone (3) with a tread (4), a reinforcing structure (5) extending between the sidewalls and passing through the crown zone, the portion of the sidewalls (2)that is axially exterior to the reinforcing structure (5) comprising an insert (6) that includes a first elastomer composition serving as a matrix in which a second elastomer composition derived fromrecycled tires is distributed in a substantially uniform manner, the proportion of the second composition being greater than or equal to 40%, and the insert (6) being axially exteriorly covered by aprotective layer (7).

Description

technical field [0001] The present invention relates to tires. The invention relates more particularly to tires composed of a high proportion of powder from recycled tires. Background technique [0002] The field of tires is limited by many requirements. This is because tires must provide assurance of safety, durability and good performance characteristics. [0003] Tires suffer a great deal of external damage, for example from potholes or road surfaces. Therefore, it is important for them to have high strength. [0004] In addition, environmental concerns have led to the current need to develop more environmentally friendly products. It is especially known to use rubber compound powders from recycled tires. The powder consists of the residues of worn tires (or new tires with manufacturing defects) that have been dismantled by using specially designed machines so that the vulcanized rubber material can be recovered and Extract fabric and metal reinforcements. The extr...
