A tire with a cellular layer is provided. The tire includes a tire structure formed of at least one crown extended by two sidewalls and two beads. A base of each of the two beads is configured to be mounted onto a rim seat. The tire also includes a carcass-type reinforcing structure anchored into the two beads, and a layer that includes a cellular material, also referred to as a cellular layer. The cellular layer is positioned on an inner wall of the tire structure, such that the cellular layer is bonded to the tire structure over at most over 20% of a surface of the cellular layer and is not bonded to the tire structure elsewhere on the surface.

Tire with a cellular layer

A tire with reduced rolling noise includes a tire structure formed of at least one crown extended by two sidewalls and two beads. A base of each of the two beads is configured to be mounted onto a rim seat. The tire also includes a carcass-type reinforcing structure anchored into the two beads and an additional layer bonded to an inner wall of the tire structure. The additional layer is bonded to the tire structure at its edges and the rest of the additional layer is not bonded. The additional layer includes an inflation valve.

Tire with reduced rolling noise

A tire includes, among the conventional tread pattern elements, at least one measuring element having a central zone and an encircling zone. In normal operation, the central zoneof a measuring element slides over the ground while, conversely, the tread as a whole does not slide over the ground. Measurements are carried out of the maximum adherence potential with the ground, at any moment, due to the central zone of a measuring element. In an alternative embodiment, the measuring element may comprise a circumferentially extending rib(s) or tread block(s) whose ground contact surface(s) is spaced at a lesser radial distance from the wheel axle than the spacing of the ground contact surfaces of the conventional tread blocks.
