Wider rim on existing stock tires, Any FE cons?

Im looking to buy a lighter wheel for my 2012 Yaris, it comes stock with 15" steel rims that are 5.5" in width and Bridgestone Turanzas (P175/65R15 84H) on them. I'm looking at the Konig Zero 15" aluminum rim Z156T04385 that is 6.5" in width. Can I use the Bridgestones on the Konigs even though the rims are 1" wider? If the tire fits on the rim and works properly, are there any FE disadvantages to the wider rim and same tire?

Any info would be appreciated!!

FE? This is more about the particular tire, not the width of the rim.

When your rim is wider than the tire, you always run a higher risk of scraping the wheels on a curb or pothole. I always like a bit of tire sticking out past the wheels myself. In addition, narrower wheels are going to be lighter.
