i wouldnt do it, but know people who have.
personally ide just sell the other 3 wheels seperatly, or try buy one wheel that is needed, my mate cracked an alloy, couldnt buy just one and a new set of 4 was out of his budget so he sold them individually, after a few months hed got rid of them all to people in the same situatiuon as him, ended up selling the three for more than he bought all 4 for.
