Just cut away in the middle of the spokes, working your way around- wear eye protection and lay the wheel down away from you so the nipple ends of the spokes don't come flying out of the rim and hit you or someone else. This can happen until most of the tension is relieved from the wheel, which will be when you're nearing halfway around. Leaving the rim strip on or wrapping with strong tape can help contain the spoke ends. Most common pliers/side cutters are a bit weak to deal with the stainless so you may have to work it. I use high leverage hardened side cutters for this. Also, some of the Vice Grip pliers have OK cutters built in.
