1970 DUSTER WITH DISC BRAKE CONVERSION WHEEL HELP

The biggest would be a 205 70. Myself I would use a 195 75 on 6 inch . Here are 225 70 on 7 inch we put on taken from my Roadrunner. You can fit a bigger tire on a dart. Dusters are tight. Lost my car because of these wheels being to big and no room for failure. I usually always had skinnies and slicks.
