Edit: The rim in question is the Sun Ringle Rhyno Lite 26x2.00 with 36 holes.
Sniker--whatever you do, don't grind your rim---but DO please watch this excellent video that shows clearly the technique to work with hard rim/tire combinations
oh, and buy some inexpensive PEDROS tire levers, they are usually yellow and come in a pair, and are super super strong.
but the concept in the video is what others have described, and with some old straps, it REALLY makes all the difference
also, at the very end of slipping the last part of bead on, sometimes putting a bit of soap on the lip edge for a the last 5 inches or whatever can help with that last bit slipping over easier--but gaining those precious extra mm's from the technique shown in video is the main help.
