I've got a 2014 f150 fx4 super crew short bed. I was wondering if with a 6" rough country lift will 37" mickey thompsons and 20x12 rockstar II rims fit? If not what is something similar that will fit? Here are the links for the rims and tires.

With that much offset on those rims you'll be lucky if a 35" tire fits, much less finding a wide enough tire to fit a 12" wide rim.

Typical fitments are 35x12.50R20 on 20x9 wheels with -12mm offset.

That will be the easiest setup to find and the best fit but if you really want those wheels/tires you are going to have to get a little more lift.

Thanks for advice and I'm new to this but the tire description says it requires rims 11-13 in wide. Also wouldn't the bigger offset make the tires fit easier since they stick out farther? I could be very wrong though lol.

To the contrary unfortunately. Makes them more likely to rub in a turn. The further out you stick your wheels the smaller the tire you can fit generally.

Those tires would fit those rims perfect, but they wouldn't fit your truck. A 35" tire may not even fit with that wheel and you would be hard pressed to find a 35" tire wide enough to fit it as well.
