Wheel and tire combo on a 72 Duster
A 275/60/15 fits. I did it myself. I’m is a 28 inch tire and it is very close. I don’t see a 29 fitting unless you can make sure it is in the wheel well really well. Still, the front of the tire may very well rub on the car body by the front spring hanger. If there is a way to get a 29 inch tire to fit without rolling or moving the metal, I don’t know what it is.
