2013 AC 5 Lug Wheel/Tire Suggestions Needed

I have a 2013 AC 5 Lug 2WD. When this set of tires find their end of life, I would like to find a set of wheels and more importantly tires that will fill the wheel wells a little bit more than the stock. I don't want anything too big, as I am enjoying my 26mpgs. Any thoughts or suggestions?

 

I put 2010 17" Highlander wheels on my 5 lug AC with 245-65-r17 tires a few days ago and really like how it looks now.

 

Pics??

 

Here ya go. Picked the wheels up on craigslist.

 

That looks nice. You know your mpg difference with those new tires? And what size are those tires?

 

Tires are 245-65-17 Only had the tires on for a week now so don't know about the MPG.
