Hard to beat 15" traklites.. 16" tire selection is worse than 15.
Cheaper and lighter tires, also 15's the rim where most of the wheel's weight is, its closer to the center so lb for lb the wheels will spin up easier.
16's and 45's do look good though. With 17's and 40's you start getting that rubber band tire look.. You have to be pretty low to make that look right.
