It might take 4 or 5 tries and your hands might be sore. Watch this guy on the Continental video from minute 6:00.

It can be hard work if you don't look like that Continental Guy. ����
+1 -Excellent point, may not be obvious to all. Stretch the tire as much as possible, evenly from both sides the moment you insert the stem. and never let up on the tension. If you haven't been doing this rigorously, it will probably give you the extra cms. you need.
