Yeah they should be. Black steelies and XJ's always work out.
The 3.75" backspacing on those will also do well, however there are a couple things to keep in mind. They will be sticking out further than stock, plus with the big *** tire, you will not be road legal unless you have huge fenders to cover them up (in a lot of states, anyway). Secondly, the further the wheel puts the tire away from the axle, the more leverage the tire has on your ball joints. If you have a locker in the front, the possibility of pulling the ball joints apart is increased if you get in a really tight jam.
