The wheel mounting configuration for the specified vehicle is a crucial specification when selecting aftermarket wheels or replacing existing ones. It defines the arrangement of the lug nuts used to secure the wheel to the hub. Specifically, the 2012 model year of this popular sedan utilizes a 5×114.3mm (or 5×4.5 inch) configuration. This indicates that there are five lug nuts arranged on a circle with a diameter of 114.3 millimeters.
Understanding this parameter is paramount for ensuring proper wheel fitment and vehicle safety. Using wheels with an incorrect configuration can lead to wheel detachment, potentially causing accidents. Historically, this particular specification has been a common standard across various Toyota models and other manufacturers, reflecting its reliability and effectiveness in distributing wheel load and maintaining structural integrity. Adherence to this standard simplifies wheel replacement and allows for a broader selection of compatible aftermarket options.
