To be absolutely certain, you must check one of the following:
* Your vehicle's owner's manual: This will definitively state the correct bolt pattern.
* The sticker on your driver's side doorjamb: This sticker usually contains tire size and other important vehicle information, including the bolt pattern.
* The wheel itself: The bolt pattern is visible on the wheel.
* Your existing wheel: Measure the distance between two bolts, then multiply by two.
Do not rely solely on online resources to determine this, as there's a chance of inaccuracies. Always double-check using one of the methods listed above.
