Have the same problem with the rear wheel. I had to use vice to break the bead and change the tire. It really sucks. One of the tire workshops in Kazakhstan could not break it with proper tire change machine. I know that this is for safety reasons, but I think that Yam engineers overdid it. The good thing is, that when you get flat, one side of the tire goes out from the bead so that you can take out the tube. I am seriously considering to change the rear to excell rim when I come back to Europe, unless somebody knows some better solution...
