Default Tire Help!

I have been trying to search the forum, but haven't been able to get a precise answer. So I am asking for some help.

Right now I have the stock 255/65/17 on my 2010 Crew f150 (flex fuel)

Looking to get 285/75/17 on there.

A couple questions...

1. What will my MPG drop down to? I have heard/read i will get 10-12 mpg and now I am getting 15-16mpg. If true, and my calculations are correct, I will lose roughly $20 worth of gas per tank?!?

2. If I get the bigger wheels will dealerships calibrate the system to fix my speedometer and odometer?

I want the bigger, rougher look, and the wifey says no to a lift, so I figured... Bigger tires and leveled front will work for a while!

Any help is very appreciated!

Sorry if all this has been discussed, just hard to search through on an IPad. Thanks all!
