* Most common: A 2004 F-150 will likely have a 6-lug pattern of 5x5.5 inches (or 5x139.7 mm).
* Less common (but possible): Some heavy-duty versions or special models *might* have an 8-lug configuration. However, this is much less common for that year.
To find out definitively:
1. Check your owner's manual: This is the most reliable source of information.
2. Look at the existing wheel: The bolt pattern is usually stamped on the wheel itself.
3. Check the sticker on the driver's side doorjamb: This often lists tire size and other vehicle specifications, potentially including the bolt pattern.
4. Use a reliable online vehicle database: Websites specializing in vehicle specifications can help you find the information based on your VIN.
Don't rely solely on general information like this; always verify with one of the methods above. Using the wrong bolt pattern can be dangerous.
