A speed evaluation system is provided for assessing a speed of a vehicle. The speed evaluation system includes a wear measurement system, which assesses a state of a tire of the vehicle. The wear measurement system includes a casing placed on a ground surface. The speed evaluation system further includes a timing device that determines at least two instants of passage of the vehicle over two distinct or non-distinct points of passage of the casing of the wear measurement system, and a processor that calculates, as a function of the instants of passage and of dimensional data of the casing and/or dimensional data of the vehicle, a speed of passage of the vehicle over the casing. A method of implementing the speed evaluation system also is provided.

There is provided a computerized system comprising a processing unit and associated memory configured to obtain a three-dimensional dataset informative of at least part of a tread of a tire, and determine, using the three-dimensional dataset, data informative of tread depth of the tire.

A tire characteristic value measurement apparatus (100) includes a support arm (124) which is provided in vertical movement means (111 to 121). The support arm (124) bears a tire (T) on a roller conveyor (101) from below and has electrically insulative properties. The tire characteristic value measurement apparatus (100) further includes electric resistance value detection means (125 to 139) which is provided in the vertical movement means (111 to 121). The electric resistance value detection means (125 to 139) detects an electric resistance value of the tire T borne by the support arm (124).

A device for measuring tread depth of tyres, wherein in use a tyre can be driven over the device in a first direction, the device comprising: a light source arranged to illuminate the tyre; an obstruction extending in a second direction substantially perpendicular to the first direction and arranged to partially block the light emitted from the light source such that a shadow is cast on the tyre when the tyre is located above the device, and such that the shadow is cast on the tyre in a direction substantially perpendicular to the tread of the tyre; and a camera arranged to view an illuminated section of the tyre.

A wheel assembly of a vehicle (e.g., a forklift or another material-handling vehicle) is monitored to obtain information regarding the vehicle, including information regarding the wheel assembly, which may be indicative of how the vehicle including the wheel assembly is used (e.g., a duty cycle of the vehicle and/or the wheel assembly), a state (e.g., a degree of wear) of the wheel assembly, loading and shocks on the wheel assembly, and/or a state of an environment (e.g., environmental temperature, a profile, compliance, or other condition of an underlying surface beneath the wheel assembly), and which may be, for example, conveyed to a user (e.g., an operator of the vehicle), transmitted to a remote party (e.g., a provider), and/or used to control the vehicle (e.g., a speed of the vehicle). This may improve use, maintenance, safety and/or other aspects of the vehicle, including the wheel assembly.
