The present invention relates to a novel tire safety monitoring line device which allows for automatic and continuous tire tread monitoring. The device comprises a plurality of dye-filled or paint-filled capsules embedded within the tire tread at differing tread levels. As the tire tread gets low, the capsules are exposed, breaking open and releasing the dye/paint. Thus, the colors of dye/paint released indicate differing tread levels, which alerts a user as to the tire tread level of their vehicle tire.

A pneumatic tire includes a surface and is rotatable about a center axis. The surface of the pneumatic tire includes a ground colored region including a surface of rubber, and an image recognition belt region including a colored region provided in a circumferential direction of the center axis.

A shoe for analyzing a component is provided. The shoe includes a housing, a NDT probe disposed on a side of the housing, and a shoe interface. The shoe interface is disposed at the side of the housing and contacts the component during the analyzing of the component. The shoe interface separates the NDT probe from the component during the analyzing of the component and moves along the component during the analyzing of the component. The shoe also includes first and second wear indicators. The first wear indicator indicates that the shoe interface is usable during the analyzing of the component. The second wear indicator indicates that the shoe interface should be replaced. Both of the wear indicators are configured similar to the shoe interface and move along the component while the shoe analyzes the component.

A tire (1) comprising a tread (8), this tread comprising at least one channel (2), at least one wear indicator (3) disposed on the bottom of the channel (2), the wear indicator comprising a contact face (7) intended to come into contact with a road surface when the tire reaches a wear limit, the channel (2) comprising a texture (4) surrounding the wear indicator (3) and contrasting with the contact face (7) of the wear indicator.

The device for monitoring the wear of a tread during running comprises at least one internal cavity intended to form a void opening on to a tread surface after predefined partial wearing of the tread, this tread comprising a wear limit corresponding to a maximum thickness of wearable material, this device comprising a measurement well opening on to the tread surface, this measurement well having a bottom formed of a first part and of a second part which are offset from one another in the depth, these two parts of the bottom being situated at different distances with respect to the tread surface when new.

An object is to make it make it possible to, before a protecting layer is exposed, visually recognize that a final stage of wear of a tread has been reached. A pneumatic tire (10) for an aircraft has: a carcass ply (12) that spans between a pair of bead portions; a belt layer (14) that is provided at a tire radial direction outer side of a crown portion (12A) of the carcass ply (12); a protecting layer (16) that is provided at a tire radial direction outer side of the belt layer (14); a tread (18) that is provided at a tire radial direction outer side of the protecting layer (16), and at which ribs (30, 32, 34) are demarcated and formed by circumferential direction grooves; and filaments (20) that are provided between the protecting layer (16) and the tread (18), or within the tread (18), that extend in a tire axial direction, and that are disposed with an interval therebetween in a tire circumferential direction.
