A5 Wheels on an '04 A4 ???

What width are they???

Think you would need spacers

Hi, Sorry this post is a little after the event, but I've just joined the forum. You definately don't need spacers. I bought a set of these 18" A5 alloys, fitted with Michelin Sports for my A4 B6 Avant. Because they have a really shallow offset of only 29mm they actually 'poke' out beyond the arches! On the rear the tyre edge is just about flush with the top of the arch. At the front the tyre rim pokes out 12mm. It doesn't sound much and I believe 30mm is the max that they can legally poke out. They certainly rub the arches if you happen hit a pot hole. I'll post some pics later if you like. TerryO.
