The arrangement of the lug nuts on a 2006 Scion xB’s wheel hub follows a specific design, essential for ensuring the wheel is properly and securely fastened to the vehicle. This configuration, characterized by the number of studs and the diameter of the circle they form, directly impacts wheel compatibility. As an example, a measurement of 5×100 indicates five studs positioned on a circle with a 100mm diameter.
Maintaining the correct wheel mounting configuration is crucial for vehicle safety and performance. Selecting wheels with an incorrect arrangement can lead to wheel instability, vibrations, and potential damage to the vehicle’s hub and wheel. Historically, adherence to the designated wheel mounting configuration ensures that aftermarket wheels and replacement wheels meet the vehicle’s engineering specifications, promoting reliability and preventing accidents caused by improper wheel fitment.
