Can't get Tyres on my Rims...

I know this is pretty pathetic, so sorry for that... :oops:
I'm converting my old MB in to a commuter, bought some Continental Sport Contact Reflex Tyres (26x1.3) to improve ability on the road but I just can't get them on to my rims (Mavic 717).
I even decided to risk a tube and tried levering them on without any luck.
Am I doing something stupid? Are these tyres designed for slimmer rims?

I've used it twice now and it work a treat.
I haven't had chance to have another go at the tyres, but I'm liking the look of that tool, will get one ordered. Thanks very much!
