A body with New Challenger Wheels

Why are they advertised as 5x4.5 by Dodge. But when you go to websites to buy the rims they say 5x115 is the rim size for Chargers, Challengers, and 300's. The Avengers and Nitros are 114.3 which are actually 5x4.5. But they are advertised as 5x 144.3 by dodge.

From the other post the 114.3 and 115 will bolt up to each other if I understand it correctly. Right?

Is the original 5 x 4.5 a 5 x 114.3 or not?
