Will 285/70/17 fit with my setup?

What is your mpg with the bigger tires . I have the same truck but it's a long bed and put a 2 inch level kit on the front. I want bigger tires

 

I've only had the new tires on a week but i haven't noticed a huge difference on gas mileage. I think they ride better then the smaller tire....I have 2" levelers, also 2" blocks and shocks in the rear.

 

I have 285/70/17 goodyear duratrack's. 1 inch wheel spacers, 3 inch lift, they rub a little when tight turning. I got 22mpg on a trip to oly and back about a hundred miles. I filled up before leaving and filled up when i got back. The mileage lost was in the tire diameter, the truck records less miles. So I used gps to calculate mileage. My truck has 172,000 miles. I am very happy with how it does on the road for a 4x4 and an automatic.

 

I have same size wheels, no issues yet. I think they use spacers for this kind of rim

 

Gauged my gas mileage for the last two weeks... Got a bit over 19 mpg, in the city...with 285/70/17s....Don't see much of difference at all in gas mileage. Nothing to worry about at least.
