* Check the owner's manual: This is the most reliable source.
* Look at the wheel itself: The lug pattern is usually stamped on the back of the wheel.
* Measure the existing wheel: Use a ruler or calipers to measure the distance between two lug holes that are opposite each other. Double this measurement to find the bolt circle diameter.
Don't rely solely on online information as variations exist depending on trim and options. Always confirm with your vehicle's documentation or the wheel itself.
