Push the upper bead into the well with your foot/feet/toes, at the same position, lets call that 6 o'clock; insert two levers side by side at 12 o'clock, where the valve just happens to be. Only the tips of the levers need to be in the tyre, and if there is a tube be careful you don't pinch it with the lever. When you have the levers pulled back across the rim, remove one lever. You may have to release some pressure from the lever to do this. Reinsert the lever you removed, about 2-3" from the lever still in the tyre, repeat until the bead is loose. It gets easier with each bite. Once the first bead is completely removed, take out the tube (if applicable) then stand the tyre and rim vertically with the remaining bead in the well of the rim. Insert a lever between the top of the rim and tyre and pull the lever to horizontal; this is usually easiest if you're standing on the side that you are removing the tyre from. You may need to put your foot against the top of the rim as you pull the lever. When you have the lever horizontal, bash the bead with a rubber mallet, alternating each side of the lever.
Hope this is some help to you, it's my first time cyber tyre changing. Let me know if it works for you, then we'll go on to lesson #2 .....putting the beggars back on. ;)
