Building the wheels: these rims were not as flat and round as other rims I have built wheels out of, but typical, I suppose of Sun rims like CR18 and M13II. They obviously can be made round and true, but it takes more fiddling than Open Pro, in my limited experience.

So, the answer is that with 32 or 36 spokes (I don't know what you have), you are in no danger at all of hurting these rims, which are pretty darn stout. Sssuming reasonable care with curbs etc. Also assuming that you have reasonably high and uniform spoke tensions.
