Post your wheel and tire combos.

Figured I would post in here before I start a new thread.

But I've got a 67 Dart GT and was curious if I can stuff a 18x8 or 18x7 with maybe a 35 or 40 series tire on my car? I'm wanting to put the absolute biggest wheel without doing a mini tub or front suspension modification!!! Any and all help will be greatly appreciated!!!!
