They would not. The maximum wheel width that BFG recommends with this tire is a 9.5" wide wheel. Most tire shops won't mount and balance tires that are more than a 1/2" smaller than the wheel, and practically no manufacturer recommends using a wider wheel than the width of the tire. If you're going for a stretched look on a 12" wide wheel, then the minimum tire width we recommend is a 11.5" wide (295 wide) tire.
