Common lug patterns for Dodge Ramchargers of that era include:
* 5x5" (5 on 5 inch) or 5x127mm: This was a very common pattern.
* 6x5.5" (6 on 5.5 inch) or 6x139.7mm: Less common, but possible depending on the trim level and options.
Do not rely on online sources or generic guides without verifying with your vehicle. Using the wrong lug pattern is incredibly dangerous and can lead to wheel failure.
