Wanted: Off-road tyres, on wheels

[G r a h a m]

I'm looking for a second set of wheels, with off-road tyres on, for my SIII. These are purely for off-road (and maybe snow) use - I already have a good set of road tyres - so they don't have to be in great condition, though naturally they need to have enough tread to be useful, and not be about to break up! Oh, and not too expensive. Anyone got anything they'd like rid of?

Preferably not too far from Edinburgh, though I'd be prepared to travel up to a few hours.
