I'm about to purchase new wheels for my 14' Challenger RT I'm gonna go with 20x8.5 +14 offset on the front with 245/45 was curious what offset and tire works on the back.. my tire shop reccomended 20x10 +2 offsett with 275/40 . I have no intentions at this point to lower my car, so I want to have a tire on the rear that will be close in sidewall height if not a lil more. Thanks

Ive got 20 x 10 +25 in the rear with 274/40. Fit is great. I am lowered too.

So would +25 be a lil less lip on the outside of wheel pushing more wheel out .. or would this be more to the inside pushing the wheel into fender well?

+25 will be ideal for a 20x10 rear. The tire won't poke out and shouldn't rub on the inside either.

+2 offset will push it out towards the outer fender too far, you would probably end up having to roll your fenders. +25 offset is ideal for the rear of Modern Mopars.

I've got a lot of information in here:

The factory reproductions have a a +18 offset and are used by a ton of members on this site. No problems at all especially if not lowered. The 275 will sit flush with the lip.
If you want to have it tucked...go with a +25 offset.
