Please clarify. Are we talking Charger or Roadrunner? What year?

295's on the rear

Bad advice! 295's will NOT clear with 51mm (2 inches) of negative offset. You will almost certainly hit the outer wheel lip. That's like 3 inches of back space.

For that much tire, you need zero offset, or maybe 12 mm of positive offset... or air shocks.

275 60 15s will be real close to the outside lip with that much negative offset, but it's been done.

Again, you need to post some specifics about your vehicle.
