How do I fold a bicycle tire? I have Race King (continental) 2.2 MTB 28" tires that I need to store until it's winter and snows again. They are foldable, and I planned to store them in their original boxes, but how do I properly fold them so they fit in the boxes like they did when they were new? 

I've tried to just fold them, but they don't fit in the boxes. I need a good description of how to fold them, and pictures are welcome.
If you can't figure out how to fold it back like it came, you can try a method of looping it 3 times to fold it in to a smaller size which works for non-folding tires as well.
