In an example, a vehicle tire includes a tread portion, a sidewall portion, and a sensor module for estimating one or more parameters of the tire. The sensor module includes a detector patch that includes one or more capacitors, each of which has an electrostatic capacity that is variable due to at least deformation of each capacitor. The sensor module also includes an electronics unit connected to each capacitor and configured to control the sensor module. The detector patch is adhered to an inside of at least one of the tread portion or the sidewall portion. At least one of the capacitors is located on the inside of the at least one of the tread portion or the sidewall portion. The electronics unit is configured to estimate at least one of the parameters based on the electrostatic capacity of each capacitor.
