Abstract: A vehicle tire monitoring methodology is based on embedding into a tire at least one tire inductor coil with multiple circumferential windings. A tire condition that causes deformation of the tire, causes deformation of the tire inductor coil. A tire condition (such as pressure, speed, damage or deterioration) can be monitored by acquiring tire coil response measurements corresponding to an inductive response to the tire condition that causes deformation of the tire, and thereby deformation of the tire inductor coil, and then converting the tire coil response into data representing the tire condition. Multiple circumferential tire inductor coils can be embedded (such as into the tread and/or sidewalls), so that tire monitoring can involve acquiring respective tire coil responses corresponding to a tire condition that causes differential tire coil responses (such as steering direction), which can be converted into data representing the tire condition.
