I have 2 sets of wheels and tires for the Duster, one with drag radials (295x50R15) and the other with slicks (29x10.50). They are 15x10 and 5" backspace for the DR's and 5.5" backspace for the slicks and fit fine (tucked with no poke). I just want them tucked in more now that I have mini tubbed the car.
