* 5x4.5" (5x114.3mm): This is the *most likely* bolt pattern for your 2000 Ford Ranger, especially for 2WD models.
* 6x5.5" (6x139.7mm): This is more common for 4x4 models.
To be absolutely certain, you should:
* Check your owner's manual: This is the best source of information.
* Look at the existing wheel: The bolt pattern is usually stamped on the wheel itself.
* Check the wheel hub: You might be able to see the bolt pattern directly on the wheel hub.
Don't rely solely on online sources as there's a chance for inaccuracies. Always verify the bolt pattern before buying new wheels or tires.
