The wheel fastener configuration for the specified vehicle and model year consists of five studs arranged in a circular formation. This arrangement, technically termed the bolt circle or pitch circle diameter (PCD), dictates the precise spacing required for aftermarket wheel compatibility. The PCD for the 2009 Toyota Camry is 5×114.3mm, which translates to five lug holes spaced equally on a circle with a diameter of 114.3 millimeters (or approximately 4.5 inches).
Maintaining the correct wheel fastener specification is crucial for vehicle safety and performance. Using wheels with an incorrect PCD can lead to vibration, damage to the wheel studs, and potential wheel detachment. This specification is a key factor in ensuring the secure and balanced attachment of the wheel to the vehicle’s hub, contributing to stable handling and braking. Furthermore, understanding this specification simplifies the process of selecting compatible replacement wheels, whether for aesthetic upgrades or necessitated by damage.
