You can rotate them, if you don't re-learn the new positions it will not automatically learn their new location. Lets say if you rotate and cross the non driven wheels and your left rear goes low it will tell you the right front is low because that is where it thinks it is.

On most G.M. cars/trucks you can re-learn them by initializing the re-learn and dropping the pressure on each tire in order, LF, RF, RR, and LR last. It will honk when it learns the new location.
