Somebody help me put the sh!t back in the horse....

I think my wife is going to kill me in my sleep.

So I bought some tires and wheels for my truck, or so I thought.....

I have a set of wheels and tires for a 4X4 pick up, the wheels are 8X170mm Ford pattern for 1999 to 2004 Super Duty trucks.
I happen to have a 2005 with ginormous brakes and the 16" wheels no gonna fit.... Dammit.

They are near new, if these have 5,000 miles on them I would be utterly shocked.
I have the lug nuts (Gorilla lockers) the center caps, they have armored stems and chrome caps.

I need to get $800 for them, no BS, I would consider a trade for wheels tires for my '05 with money going either way.
Looking for LT305/70R17 with a fairly aggressive tread pattern.
I literally can't sell these any cheaper, this is what I have in them, the tires are on sale at Pep Boys right now for $267 each, then they have to be mounted balanced and these already have very nice wheels.
Help me out brothers. In a real pickle here.
