* Bolt Pattern: The number of lug nuts and the distance between them (bolt pattern) are almost certainly different. Dodge Chargers and Oldsmobile Cutlasses use different bolt patterns throughout their model years. This is the biggest hurdle. The wheels won't even mount correctly.
* Wheel Offset: The offset (how far the wheel's mounting surface is from the center line) will likely be different. An incorrect offset can cause rubbing against the suspension, brake calipers, or fenders.
* Center Bore: The center hole of the wheel (center bore) might not fit the hub of the Cutlass.
* Hub Size: The hub size and diameter on the Dodge Charger may not match the Cutlass.
To know for sure, you'd need to find the specifications for both the Dodge Charger rims and the 1984 Oldsmobile Cutlass's wheel hubs. This information is usually found on a sticker inside the driver's side doorjamb or in the owner's manual for the Cutlass, and potentially stamped on the Dodge Charger rims themselves. You need the bolt pattern (e.g., 5x114.3), center bore diameter, and offset for both to compare. Even then, professional advice from a tire shop or mechanic is recommended before attempting to mount anything.
