Thanks guys...

So if I buy the CX with 37s on it I can just buy a set of 32s at the same time and swap them over when I know I'm gonna go on a fairly lengthy road ride not involving offroad? Or indeed when I know I'm gonna be doing a fair bit of offroad I may just buy a set of 45s and do the same?

Is there seriously no safety impact of doing this?
Fiery suggested you check Sheldon Browns Chart. It is straight forward to me...measure your inner rim width and follow the suggestion on the chart.
