Tires OEM Audi or FEDERAL

formoza 165 45's.... i gotz 2 sets. they are great. and fairly cheap.

I got some Federal 215/40/18's from Josh @ Sterling Tire and I think they're great! They stretch well, have a bit of a lip protector and aren't loud. The traction is great, especially in the rain.

IIRC he said it dropped him like two more inches and it's VERY stiff.

My car on 15x8's is sporting 195/50 15's and the tires are slightly stretched-- not too stretched in my opinion but just help to round out the sidewall a bit
