* Bolt Pattern: This is the most crucial factor. The 2004 Ford Freestar uses a 5x114.3mm (5x4.5") bolt pattern. Any replacement wheel *must* have the same bolt pattern.
* Wheel Diameter: Freestars came with various wheel sizes (typically 16" or 17"). You can use the same diameter, or possibly go slightly larger, but going smaller is usually not recommended. Larger diameter wheels may require different tires and could affect speedometer accuracy. Check your existing wheel for the diameter.
* Wheel Width: The width (e.g., 6.5", 7") affects tire fitment. While you can be slightly off, significant differences can cause rubbing. Check your existing wheels.
* Offset: This is the distance between the wheel mounting surface and the centerline of the wheel. The offset will be stamped on the back of your current wheel. Using an incorrect offset can cause clearance issues.
* Center Bore: This is the diameter of the central hole in the wheel. It should match the hub bore of your Freestar. If it's too small, the wheel won't fit over the hub. If it's too large, you'll need hub-centric rings.
To find interchangeable wheels:
1. Check your existing wheel: Look for the markings on your current wheel. They will specify the bolt pattern, diameter, width, and offset.
2. Use online wheel databases: Websites like Tire Rack, Discount Tire, or similar allow you to search for wheels based on these specifications, ensuring compatibility with your Freestar.
3. Check forums: Online forums dedicated to Ford Freestars can be a great resource. Members often discuss wheel upgrades and compatibility issues.
In short: While you might find visually similar wheels, don't rely on appearance alone. Always verify the critical dimensions listed above to avoid problems. Incorrectly sized wheels can affect your handling, braking, and potentially cause damage to your vehicle.
