Here's what you need to check:
* Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. Find this information for both the 2002 convertible and the 2004 Sebring donor wheels. They *must* match.
* Wheel Offset: This is the distance between the mounting surface of the wheel and the centerline of the wheel. A significant difference in offset can cause problems with fitment and potentially rubbing against suspension components. Try to find the offset for both sets of wheels.
* Center Bore: This is the diameter of the hole in the center of the wheel that fits over the hub. The center bore of the wheels must be the same size or slightly larger than the hub of the car to allow for a hub-centric installation. Again, get this measurement for both.
* Tire Size: Even if the rims fit, the tire size needs to be compatible with your car's specifications. Using a different tire size could impact your speedometer accuracy, handling, and potentially cause damage to your vehicle.
You can usually find this information on the wheels themselves (often stamped), in your owner's manual, or online using resources like tire size websites or wheel specification databases. If you can provide the exact specifications of both the wheels and the car, I can help you determine if they are compatible.
