69 Dart Swinger Wheels /Tires

72 Swinger here with 245/60x15s on 15x8s with 4 1/2" backspace, left about 3/4" to the springs. For peace of mind I modified the fender lip for more clearance, 1/2 - 3/4" worth. 195/70x14s on the front if I remember right on 6" rallys. A 255 might fit in the back, sure would be close on the fender side though.
