Tire wear affects safety and performance of automobiles. Past solutions are either inaccurate, require sensors embedded in tires or are prone to road debris. Osprey proposes a radio frequency tire wear sensing system design, based on automotive millimeter wave radars, to overcome challenges related to road debris. We design super resolution algorithms to measure millimeter-level changes due to wear and tear. In addition, the principles used also open up solutions for detecting and localizing harmful metallic foreign objects in the tire.
