The Arnold Clark group has offered me four 185/60/15T Continental WinterContact TS 800 winter tyres for £299 (the standard package offer as per its website) and says it can provide a set of four original Clio steel wheels with 17mm bolts for another £100, total £399. I realise I can internet-source the tyres for about £50 less, but finding separate wheels is, I'm amazed to find out, rather a problem. I'd appreciate your advice on the above offer and where I can find the best advice for storage of summer wheels and tyres - on their sides or upright, turning every few weeks etc.
