A method of measuring thickness of a material generally includes transmitting an oscillating signal from a first pad, through the material, to a second pad, and measuring the signal reflected back to the first pad. The material may be homogenous or heterogeneous, and has dielectric properties. The signal has its frequency varied over time so that the frequency response of the system (the first pad, the material, and the second pad) may be analyzed. The resonant frequency of the system is determined. The thickness of the material is determined based on the resonant frequency shift caused by a change in thickness of the material. The present invention may be advantageously employed to measure the thickness of a vehicle tire or other material. Related apparatuses are also disclosed.
