Having seen a set of S4 alloys in need of a refurb with duff tyres sell on ebay for £340 I am considering selling my wheels for some 19's. I've had a few people pm me asking how much I want for them but not really a clue? Can someone advise?! They are all in great condition, not mint by any means but definitely not needing a refurb, and all 4 tyres have loads of tread (4 Avons). Any ideas?!!
