Right, the bigger the wheel the less performance. Everyone would agree in general. I don't know if everyone races their vehicle when going to work but when I get my 22" rims they will have a lot of tire to them (the most that would fit the wheel well).
Since I wont be racing, its not a big deal. I think a lot of us wont be racing. (I'm guessing)
As you can see in the Camaro Black, there is sufficient room to add 22" rims while still maintaining a significant amount of tire to the rims... and yes, rubberband tires are a waste.
