The configuration of lug holes on a vehicle’s wheel hub, expressed as the number of lug holes and the diameter of the circle they form, is a critical specification. For instance, a 5×100 designation indicates five lug holes positioned on a circle with a 100mm diameter. This measurement is vital for ensuring wheel compatibility.
Adherence to the correct specification ensures safe and proper wheel mounting, preventing vibration, wheel detachment, and potential damage to the vehicle’s hub and wheel studs. The specification has evolved alongside the Corolla’s various generations and models, reflecting engineering advancements and design modifications. Maintaining accurate specifications is essential for both aesthetic and functional considerations.
