Being that the rims are so close in weight, if you put the same tires on both, in the same overall size (same width and diameter, just different sidewall heights), the 17s should actually get better mpg around town, and the same on the highway, as rolling resistance would be equal, and the tires for the 17" rims would then weigh less, bringing the overall package weight down.
