To be absolutely certain, you should:
* Check the owner's manual: This is the most reliable source of information.
* Look at the wheels themselves: The bolt pattern is usually stamped on the wheel.
* Check the vehicle's sticker: There might be a sticker on the driver's side doorjamb with specifications, including the bolt pattern.
Don't rely solely on online information, as there can be variations depending on options and model specifics. Always verify with your vehicle's documentation or the wheels themselves.
