They'll fit, but they'll look 'orrible and will muck up your speedo readings (and probably your handling too).
Being a larger outside diameter they could even rub on places that they shouldn't normally come near.
Personally, I wouldn't.

For those who dont know what the numbers mean:

The first number (205) is the width of the tyre in millimetres
The second is the tyre wall height as a % of the Width
The third is the rim size (in inches)

so here a 205/55R16 would be a 10% more tyre wall than the stock 205/45R16

That equates to an extra 41mm total diameter, or a 6.9% increase in overall diameter.

This means your speedo will be around 6.9% too slow.

Add to Karrots list "C" for commercial, which may be on the van tyres, and also the load index and speed rating.
So 205/45 ZR16 87W
equates to 205 tread width 45% aspect ratio.
ZR16 Z=tyres are suitable for speeds higher than 240km/h R= radial/ 16" rim
87= load index (tyre suitable for up to 545kg weight)
W speed rated to 270km/h
You may also see M+S = mud & snow (winter tyre)

Using tyres less than the spec recommended by the manufacturer may void your insurance.
