Utilization of magnetic signature of automotive tire for exploitational wear assessment

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. This specific feature of the tire can be interpreted as the magnetic pattern of the tire. The aim of the research was to determine the influence of operation on the distribution of magnetic induction around the tire. The tests were carried out on new tires and after a specific operational mileage. The obtained results in the form of spatial images of the distribution of the magnetic field force lines of new tires and after a specific operational mileage allowed to visualize the differences in their technical condition, which were not possible to observe using other research methods.
