will a 17 inch wheel use more gas

 

it shouldn't as long as your total over all circumfrence is the same (wheels and tires) and the same weight or lighter, it shouldn't use more gas.

but there are a lot of things that affect this such as rolling resistance and other things that i can't think of right now off the top of my head

hope this helps

 

Also, if you get wheels that have a larger circumfrence than stock, it will trick the VSS into thinking you have traveled less distance than you actually have. So when you go to calculate your mpg with the mileage the odometer has logged, it will appear that mpg has gone down (no to mention mph will be off too).

The opposite is true with smaller than stock circumfrence wheels, it will seem that mpg has increased.
