Utilization of magnetic signature of automotive tire for exploitational wear assessment

open access: yesDiagnostyka, 2022
The use of tires is limited, on the one hand, by their geometric wear, which is interpreted by vehicle users as the tread height, on the other hand, as a result of aging processes. There is an intrinsic magnetic field around the tire.
