Others here have probably encountered the same thing:

The spacers I used on my rear wheels are now stuck on the hub.
I was trying to put on my snow tires last night and realised I cannot get the spacers off.

Now I have a few options:
1. Penetrating oil
2. Torch (spacers are aluminum/magnesium alloy, should I worry? magnesium + heat = fireworks)
3. Hammer (vibrations)
4. Pry bar (worried about damaging the hub)

Any suggestions?

Some WD40 and a rubber mallet should do the trick. You may want to consider using something to slightly pry it off at the same time, but either way it should come off.

i'd use rubber mallet. fixed brake calipers sometimes can get caught and bind onto metal prongs on the brackets... u'd use a rubber mallet to try and bang it loose. i'd imagine u should use the rubber mallet first. next time, try to make sure the surface on the spacer and the hub/rotor is clean before u mount them. also make sure u have the right torque on the bolts... don't want to warp both the spacer AND the rotor...
