Abstract
Method for indicating attacks on a tire (1) for a heavy vehicle of the civil engineering type. This method comprises a first step of applying a retroreflective covering material (7) to at least part of at least one tire lateral face (6) allowing visual detection in an environment of darkness of that part of at least one tire lateral face (6), a second step of using the tire (1) in a mechanically aggressive environment, a third step of identifying, in an environment of darkness, the attacked zones (8) of the part of at least one tire lateral face (6) initially covered with the retroreflective covering material (7) and now devoid of the said retroreflective covering material (7) as a result of the mechanical attack experienced by the tire (1) in use.
Claims9
A method for indicating attacks on a tire for a heavy vehicle of the civil engineering type, the tire comprising a tread, the tread comprising a tread surface having two axial ends extended radially inwards by two tread end faces, each tread end face being extended radially inwards by a sidewall external face, a tread end face and the sidewall external face extending it radially inwards constituting a tire lateral face, the method comprising:
- a first step of applying a retroreflective covering material to at least part of at least one tire lateral face allowing visual detection in an environment of darkness of that part of at least one tire lateral face;
- a second step of using the tire in a mechanically aggressive environment, and
- a third step of identifying, in an environment of darkness, the attacked zones of the part of at least one tire lateral face initially covered with the retroreflective covering material and now devoid of the said retroreflective covering material as a result of the mechanical attack experienced by the tire in use.
