How to get identical animations out of phase

Hi,

I’m working on my first game and I have a car with two wheels. My wheels are identical copies of the same prefab (which has a rotating animation). When I execute it, both rotate with exactly the same phase.

How can I randomize the phase? Is it possible to start an animation at a random frame? Should I be looking at randomizing the time each animation starts? What would be the simplest/cleanest way to do it?

Thanks

If the wheels are just animated to be rotating, why not actually rotate one of them by 180 degrees in the editor?
