tire/wheel combo
 

I have a 2004 Endeavor AWD with the 17x7 wheels and 235/65 tires. I like the look of this 2012 Limited (which seems didn't make it to production), with 18 inch wheels and I think 255/55 tires. Is anyone running aftermarket 18'' wheels with wider tires? Just wondering what specs on the wheels for offset and backspace? Pictures would be great also, thanks! This is the link of the 2012 I like:
