The trick is that you need to stay up around 27 to 28 inches in diameter. That can be hard to do as a lot of 17 inch and 18 inch tires are shorter than that. If the tire gets too short it gets lost in the big wheelwells on the Mopar muscle cars.

Something like a 235/55-17 tire works really well on most Mopar muscle cars. That tire is fairly tall and it has more cross section than most of the factory tires. It is about as wide as you can go up front before starting to run into issues. You can go wider out back of course but you'll still want to find something that is the correct height.
