The tires are 215/50/R17 Kumho. They are silver on the outside, and the whole inside is completely black. I'm not a huge fan of big shiny wheels, but I believe these will look pretty good.

Last week I had a flow master 40 series installed. It's pretty throaty, and got a low rumble at idle. Up in the rpm's you can barely tell it's aftermarket in the cabin though.
