A handling machine performs a method for updating a database for managing a fleet of vehicles, during replacement of a tire on a vehicle that includes a plurality of predetermined spatial zones. The database includes a tire identifier for each tire of the vehicle and a zone identifier for each predetermined spatial zone. Each of the tire identifiers is associated with a corresponding one of the zone identifiers in the database. A zone identifier of a spatial zone containing a tire is determined when first predetermined conditions are met, and a tire identifier of the tire is determined when second predetermined conditions are met. An association in the database between a zone identifier and a tire identifier is updated if at least the first and second predetermined conditions are met simultaneously at least once.

A pressure-measurement device includes a pressure-measurement surface, which is functionally connected to a test body, and a sealed pressure-measurement housing in which the test body is arranged. The pressure-measurement surface is carried by a deformable wall of the sealed pressure-measurement housing lying at a distance from the test body. The sealed pressure-measurement housing delimits an internal space, which is a space internal to the sealed housing. The pressure-measurement device also includes a pressure-transmission object that transmits the pressure between the pressure-measurement surface and the test body. The pressure-transmission object includes a substantially incompressible material occupying all of the internal space. The pressure-measurement device further includes an energy source and a processor for processing pressure data detected by the test body. The processor is arranged in the sealed pressure-measurement housing.
