My DX55 manual has a page or so with the specs similar to what Greenland South posted above. But then there is an additional page following those specs, which shows diagrams of each 'rim-to-dish' configuration so it is clear. I'll bet yours has the same diagram.
Well my manual doesn't have any diagrams or explanation on how to configure the wheels for different widths. Just the same page that was posted earlier. So there are 4 different settings, I'm just not sure how to obtain them. Can anyone shine some light on it?

From your picture it looks like your current setting is the one on the Bottom Left or top right, depending on which side of the offset to the rim that your wheels are currently bolted to.
Notice where the hub is bolted to the rim, it is offset, not in the exact center of the rim. So depending on which side of that offset offset you bolt to makes a difference. You need to gain at least 6 inches or more to get under 72 inch width.
