Carbon Fiber is much like a cinder block in its strength. It's excellent for stress and load bearing, but direct impact (ie: Hammer or pot hole) will shatter it. Not to mention that CF shards are razor sharp. Just watch any modern day F1 car... a slight grazing of a wall or barrier and 8 times out of 10, something important always breaks.
Unless you live in a country with an excellent Department of Transportation, I would personally stick with Forged or, if you can afford it, Billet metals (which is, naturally, stronger).
Also, as long as you have a competent tire changer, or learn to do them yourself on a good quality (I always had good luck with Coates) tire changing machine and do them yourself, you shouldn't have any problems with multiple changes.
