The point where a car meets the ground and provides force and isolation is the tire. Estimation, sensing, and power harvesting are the three main areas of research in the field of tire condition monitoring systems (TCMS). The implementation of intelligent tires is highly advantageous for the reduction of disastrous accidents, CO2, and noise emissions, and also fuel consumption. Sensors mounted on the wheel hub can be used to measure longitudinal, lateral, and vertical tire forces, and pressure but available wheel transducers are expensive, hard to calibrate, and require large space; thus, they are not used for production vehicles. In-depth multidisciplinary research in areas including vehicle dynamics, control, estimate, energy harvesting, and even nanotechnology has been stimulated by the ambition to use intelligent tires.
