2010 Wheel/Tire opinion

I have been searching the site for a good setup for my needs and think I have it narrowed down and just need reassuring that its good for me. This truck is my daily driver and the only "offroad" use it will get is in snow storms or fishing/hunting. I plan on getting the TSB done with 5100's all around and possible 1.5" AAL. I definitly want a gloss black rim with possibly a little bit of silver/chrome. I also want the silent armor tires due to the all around use and mileage warranty. I want to get the best mpg as near to the stock rim/tire setup as possible so let me know what you think.

1. 17 x 8.5 rims with 6 x 5.5 pattern and -6mm offset
265/70/17 silent armors

2. 16 x 8 rims with 6 x 5.5 pattern and 0mm offset and 4.5 bs
265/75/16 silent armors

3. Not sure if it would work but stock tires with option #1 rims?

I am also trying to find a load rating close to stock in the silent armors which I believe is P but no luck yet. Any help would be greatly appreciated.

Best bet for highest millage on silent armors. Going to a larger tire will decrease mpg performance. You can curb that decrease by buying lighter & less aggressive tires and wheels, although tire weight is more important than wheel weight when mpg and brake wear is concerned.
