Hi everyone - advice please. I've got 18" Audi RS6 alloys on my T4, but want to buy another set of wheels that I can fit winter tyres to, only I'm not sure what size is best. Brakes are stock, it has been lowered but only about 60mm. If I replace with 18s will they catch the arches? Will it took rubbish if I go for 15s? Not sure what to do - am after a cheap, safe and not too bad looking solution. Cheers.
