33x12.5 on stock 16s?

Anyone running them? I'm looking for tires and 4WP has 33"x12.5 BFGs for 179.99 a piece, which is a hella good price. I've got Ford keys and 1.5" spacers to install when I get the new meats, so two questions:

A) will 33x12.5 fit on the stock 16" alloys

and

B) will they rub even with the keys and spacers?

Anyone who's running this setup feel free to chime in. Thanks.

i'm wondering about the answer to this too. would the 33's be too big for stock suspension as well or would they fit under there?

you should be able to run them but im gonna have to say you may have to trim just a little just to be safe. Anybody have any pics of this setup?
