The van I bought last week has some nice alloys on it... however the hole in the centre is about 18mm bigger than the spigot on the hub/brake.. this
means that the alloy DOES NOT sit on the spiggot...rather, it sits over it...
Is this bad?
Can I drive it like that or do I need to get some rings made up to fill the gap?
LOgic tells me its not safe, but what does the greater LB suggest?

I imagine many many people have run around without the right size spigot rings fitted, I know I have.
If you find a supplier for the brand of alloys you've got, they'll be able to supply you with a set of correctly sized plastic spigot rings
that clip to the wheel. They're normally about a tenner for a set, although if you speak nicely to the guys at a tyre fitting place that sells
the wheels, they may have some kicking about for beer money.

measure/sketch them and see if someone on here will make them for you for a few beer tokens

don't worry about it, the rings are only for helping you fit the wheels, not taking the weight of the car. After all their made of plastic....
It's the wheel nuts and their studs that carry the load. I have a few alloys (like the slot mags) where the hole is huge compaired to the hub
center and the use a metal cap to hide it.

As Whippy says - once they are located properly and tightened up, they should be fine. The issue is making sure that the wheels are properly centred
before you tighten up the nuts. The spigot ring (or correct wheels for the hubs... 
) mean that is not a problem.
Personally I would try to get some spigot rings. Failing that, could you use a home-made tool (like a hollow cone with the top lopped off) to help
centre the wheels before doing up the nuts?

I am not sure that is correct - it is the friction between the hub and wheel that carries the load - why else would you need to torque the bolts up to fifteen billion pound-foot?
I've got 19mm "universal" spacers on my wheels to correct the offset (they are Focus wheels so the offset is something like 52mm). The
spacers I bought don't have spigot rings on them so my wheels are just fitted onto the studs and torqued up. I was worried that I might get
problems with the wheel not centering correctly but in practice it seems to be fine. I don't get any vibration at all (not from the wheels
anyway...)
Just make sure you use copper grease under the heads of the wheel nuts to allow the wheel to centre itself and make sure you tighten all four nuts
down evenly and gradually. I always spin the four nuts down very lightly initially and then quite firmly and then firmer still before dropping it onto
the ground and using the torque wrench. Seems to do the trick.
Cheers,

We had to fit spigot rings to the corsa as the vibration at the rear without them was terrible even with the proper wheel nuts. The spigot rings cured the problem even though they are only 1mm or so plastic.
You can get plastic ones on ebay that do the job or its very easy to get someone with a lathe to machine some up.
Only problem i had with the ebay plastic ones is that the wheel hole had a very slight taper, i could not see it but dad in law did and it took him a
couple of mins to sort them on his lathe.
Not safe without a spigot ring IMHO, having had a wheel fall off a rally Escort shearing all 4 studs, you know it makes sense
