Did you just put stock size AT3's on, and nothing else? It almost looks like you put spacers on as well. Those AT3s really fill up the wheel well.....well. The stock duelers look like bicycle tires in comparison.
Just stock size AT3s, nothing else. No spacers, no nothing.
Though in the interests of full disclosure I might add that the Duelers were shot with considerably longer focal length than the AT3s and that affects the way they look. On the other hand the AT3 tread is really, actually wider.
