maybe. 17" wheel weight + tire weight = 18" wheel + tire? overall tire height and tread width being equal, the heavier combination could lower your gas mileage.

Depends on the tire. I lost 2.5mpg with the BFG 285s I'm running. I had Michelin 285s before this, but the tread pattern was more of a street tire than AT. The added weight and wider footprint/tread really impacted my mileage. If I went back to a 265 factory tread tire, I'd be back at 17mpg.
