i will admit that i did take a hit on gas mileage switching to 17's, but in the long run, you need to compare the savings in fuel to what style you like. if you really prefer the look and slightly stiffer handling characteristics of the larger wheels and wider tires, then the difference then becomes an academic argument.

my advice, do exactly what you like with your car. don't even worry about what others think, because opinions are like a**h*l*s, everybody has one.
