Abstract
Methods and systems are provided for determining frequencies associated with tire crown bending. The system includes a vibration generating device configured to excite vibrations through a tire. The system further includes a vibration sensing arrangement configured to sense vibrations at a plurality of sensing points on the tire. A computer is in communication with the vibration sensing arrangement and configured to determine a first frequency associated with bending of the crown of the tire based at least partially on phase differences between the sensed vibrations at the plurality of points on the tire.
