Wheels and tires....much help needed

[black2002ls]

Alright, Hopefully some of you guys are familiar with my 1/12th scale build. I am going to be hitting the drawing board again, for the wheels and tires. This time I am going to start with the tires, and then move to the wheels. I've been talking to a machinist who works almost completely in scale parts. He says that this is the way to tackle it. So I am looking for suggestions on wheel/tire combo's. If this were a real world car. It would have a TT LS7 so we are talking close to 1000 at the wheels. I want something that is going to look good and be able to hold the power. My original wheels called for 11" wheels out back and 8.5" up front. Maybe a 18/19 combo. Suggestions with pictures would be great. I want this build to be as realistic as possible.
