A fixture for testing stiffness of a vehicle wheel by measuring vibration of the wheel includes a base and a retention member. The retention member is integral to the base. The retention member defines a distal end including a distal diameter and a proximal end being proximate to the base and including a proximal diameter. The proximal end includes a plurality of studs extending upwardly therefrom for being received by lug apertures defined by the vehicle wheel thereby securing the vehicle wheel to the retention member. The distal diameter includes a ratio to the proximal diameter of between 0.6 to 0.8 to one.

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.

An information device including a capturing function uses the capturing function to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened. Then, the information device inspects whether any of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image.
