I assume the 21 and 32 were simply the previous version of the 22 and 33 listed on Mavic's site.

You can look on the manufacturer's sites to find maximum tire size and pressure as shown in the link below. A little bit of sleuthing and you could probably find the same for your rims but it is probably the same or darn close to it. You are not looking to put an extreme tire on the rim so any 700x25 should be fine.
