An at least one acoustic sensor in form of a microphone configured for coupling with a tire pressure monitoring system and tire pressure monitoring system unit sensor to generally detect an acoustic signal within a tire interior space generated by a tire as the tire travels across a road surface. The detected signal can be used by various vehicle systems to generally determine a tire condition, such as, but not limited to, tread wear, tread depth, tire health, road condition, road characterization, status of noise reducing foam, and active noise cancelling.
