Wheel size for A-Body Dodge Demon

Your bolt pattern is probably 4" (not 4.5") unless you have an 8.25 or a modified 8 3/4 that has been switched to the large bolt pattern. As for the 17s, yes, you can run them. It is just a matter of width and backspacing that you need to pay attention to. I don't know if you were asking about space requirements or actual spacers. If spacers, stay away from them.
