    Hi all, I was under the impression the tire pressure sensors for each tire measures the rotation of the tire, more pressure equals slower rotation. RPM's of the tire is proportional to PSI. Can anyone tell me if this is correct. Many thanks...

    Incorrect, it measures pressure.

    Tire speeds that are measured by the individual ABS sensors is a base GM system. Other manufacturers might also use it.
    It can be accurate except if worn tires are rotated that can throw it off. Gradual tire wear shouldn't trigger it.
