Backspace looks good. These should bolt right up. If you get any rubbing it will be in the front during a full turn or when flexed up on the trail. You might want to consider a 2-2.5" lift/leveling kit if you hit the trails often.
Here's link to some options we carry. We can set you up with a wheel and tire package if you are interested. Mount and balance would be FREE and shipping is FREE as well.
