Right, i sold the LM's off the S3 to another forum member and then bought a set of original S3 Avus wheels and tyres to put back on from a another different member. They have Regal tyres on, and i knew they weren't going to be the best but my god they're loud! I don't just mean, 'hmmm, notice a bot more road noise with those' i mean 'god are my wheels on properly'. They're ever so slightly out of balance but that can't be what's causing it so i'm going to have to change. I know on the S3 Avus 17's you need 225/45/17 but has anyone put 225/40/17 on?
