How Big of a tire can I put on my 1968 Dart with the spring hangers that move the spring in about 3/4 inch each side and what back spacing do I need. I'm going to put 15 inch Mopar rally wheels on.
I run 275/60/15s with a 15x8 wheel on my 68 Dart w/ the springs moved in 1/2". You have to nail the backspacing dead nuts to run that size tire on a Dart - it'd be safer to go with 255's. I believe the backspacing is 4.75" on my 15x8 steelies.
I have the same set up ! I may have to roll the inner well it give me a bit more room. I only have about 3/8 room on dr side!! A touch more on pass sideView attachment 1715830980 255/60/15 here with 15x7 4.25 back space. Scuff sometimes but that’s the biggest I could go with everything stock
