Im guessing thats each aye? ;-)
you can buy ready built steel wheels with tyres from www.mytyres.co.uk
I've ordered some of then on 16s with Avons on, I think they are running very low on stock and it will be a while before I get them.
I ordered on the 25th Nov just as all the snow started coming down.
Hopefully they will arrive before any snow in Jan/Feb.
