Abstract
This invention relates to tire tread wear monitoring. A sacrificial magnet portion is arranged in a tread of the tire so that it undergoes wear along with the tread and generates a useful magnetic field signal indicative of remaining tread thickness. With a magnetic field sensor arranged on or in the tire, an overall magnetic field signal is measured, which includes the useful magnetic field signal, and a superimposed interfering magnetic field signal generated by magnetizable material contained in the tire. A non-sacrificial magnet portion is used to saturate the magnetizable material at least locally so as to make the interfering magnetic field signal sensed by the magnetic field sensor substantially independent of the useful magnetic field signal sensed by the magnetic field sensor. Further aspects of the invention relate to tires, e.g., vehicle tires, featuring a tire tread wear monitoring system.
