Syncro need to have their tires within 5% (including wear) of each other's
diameter so as not to screw up the VC (viscous coupling between from and
rear diffs). BTW, it's spelled without the "H". Anyway, the theory is to
rotate all tires including the spare to get the maximum life out of the set
of tires.

You could buy 4 and get a comparably sized spare wheel. You would would have
an odd looking wheel on your van at some point of the tire rotation. If you
don't care or are willing to dismount a tire solely for rotation purposes,
you should be OK with just 4. It is just much easier and more aesthetically
pleasing to have a matched set of 5 wheels.
