What kind of rims and tires are these on this Hemi Dart?
They're just OE style steel wheels guys. I wouldn't even rule out that they're 15x7's off a Diplomat or something. Didn't some of the 1/2 ton trucks come with a 15x8 in this style? Could just be factory steel wheels.
But you can also get OE style steelies from Wheel Vintiques up to a 15x10. Just a Wheel Vintiques model 63.
