I don't know. It all depends on your purpose. If you're building a car for Redline Time Attack and you're in the Enthusiast or Street class, the widest tire you can use is 285, so there's no point in getting a 11" width wheel. Therefore, a 10" width or maybe even 10.5" width wheel would be better in this situation. A lot of 18" wheels clear the Akebonos and even the AP Racing BBK. Go check out the Robispec 370z if you want an excellent example of a purpose-built machine. On a side note, my track wheels are 18x10 all around haha. I didn't really find the need for 19's.
