* Bolt Pattern (PCD): This is the number of lug nuts and the diameter of the circle they form. Both vehicles *might* share the same bolt pattern, but you MUST verify this. A mismatch here means the wheels won't even bolt on.
* Wheel Offset: This is the distance between the wheel's mounting surface and its centerline. Different offsets can cause clearance issues with the suspension, brakes, or fenders. A Magnum's offset will likely be different from a Ram 1500's, potentially leading to rubbing or other problems.
* Center Bore Diameter: This is the diameter of the hole in the center of the wheel that fits over the hub. An incorrect center bore will either prevent mounting or require hub-centric rings (adaptors).
* Wheel Size (Diameter and Width): While the bolt pattern matches, the wheel diameter and width need to be compatible with the Ram 1500's tire size and suspension. Too large a diameter or width could cause rubbing.
In short: You need to find the exact specifications (bolt pattern, offset, center bore, diameter, and width) for both the Dodge Magnum rims and your specific year and model of Ram 1500. Then, compare those specifications to ensure compatibility. A tire shop or online wheel compatibility checker can help with this process. Don't just assume they'll fit.
