The configuration of the wheel mounting studs on the specified vehicle is a critical specification for ensuring wheel compatibility and safe vehicle operation. This specification, measured in millimeters, denotes the diameter of the circle upon which the wheel studs are positioned, along with the number of studs present. An example would be a “5×100” designation, indicating five studs positioned on a circle with a 100mm diameter. This measurement is fundamental when replacing wheels or installing aftermarket components.
Proper knowledge of this wheel mounting specification is essential for several reasons. Firstly, it guarantees that aftermarket wheels will fit the vehicle’s hub correctly, preventing vibration and potential damage to the wheel studs or bearings. Secondly, it ensures that the wheel nuts are properly torqued, distributing clamping force evenly across the wheel mounting surface. Historically, incorrect fitment has led to wheel detachment and catastrophic accidents, highlighting the importance of precision.
