Yeah, I should add that anything taller than about 29" will rub the front of the wheel opening flange.
You can either pie-slice (to keep the flange) there, or cut it away, depending on how stock you want the area to look.
I did the pie-cut on another Duster and it bought me about 1.25". It would just take a 30" tire, but tight. Charger probably has more room.
Measure, measure, measure.
Spacing the rear axle back a bit can buy you some room, being that your springs are at the rails.
