It all comes down to what you like/prefer. Every wheel/tire combo has a compromise of something.
14" and 15" wheels may get better traction at the dragstrip but they stink for handling purposes.
17" thru 19" wheels will help a car handle much better but due to the descrease in sidewall height, they aren't as good at the dragstrip.
Once you get above a 19"/20" rim combo, you start getting into rims that are just too heavy for anything more than a cruiser and less of a tire size selection. Although I'm sure the tire sizes will be catching up soon enough considering a lot of new vehicles are coming from the factory with 20"+ wheels.
My 2008 Sierra has 20" rims on it and I love them.
