Road noise and the primary cavity resonance tone (PCR): part 2

A tire study has investigated if there can be a good agreement between rolling road and real road measurements

Part 1: recap

Driving at speeds <50mph (80km/h) revealed that for light throttle the driven and undriven tires generated essentially the same level of cavity resonance tones. On a 1:20 incline at 45mph (72km/h) the driven wheel’s PCR tone was some 4dB higher in level.
