When I worked as a mechanic in the '70s we had a puller that really only worked well on steel rims. It never was that great of an idea, it's extremely difficult to do a good job on a bent rim. Aluminum will be weakened and probably start cracking soon thereafter.
I have tried straightening a Sun CR18, and the rim cracked.
