I bought the wheels and tires first and they were fitted underneath the Duster during the 4-Link mockup before ordering the Dana 60 so we could get the correct rearend width.  Check out the lefthand image above... the tires are almost as tall as the trah can! For the rear, I selected #90-514348, 15" x 14" Draglite wheels from Weld Racing. They feature 4 1/2" and 4 3/4" double-drilled bolt circles and 4 1/2" backspacing.  For tires, I selected Mickey Thompson #1562, 31" x 18 1/2" x 15" Sportsman tires and #9557 Racing Tubes for the big Sportsman tires.
For the front, I selected Weld #90-55346, 15" x 5" Draglite wheels.  These feature the 4 1/2" and 4 3/4" double-drilled bolt circles and 3 1/2" backspacing.  For tires, I selected Mickey Thompson #1572, 26" x 7.5" x 15" Sportsman tires.
The Wheelie Bars are #2016 from Competition Engineering. They ended up being shortened (width-wise) to fit around the coil-overs and 4-Link.
