The arrangement by which a wheel affixes to a vehicle hub is a critical factor in ensuring safe and proper wheel installation. For a specific year and model of a luxury SUV, this measurement defines the circle on which the wheel studs are located, expressed by the number of studs and the diameter of this circle, typically in millimeters. As an example, a designation of “6×139.7” indicates a six-stud configuration with a circle diameter of 139.7 millimeters. This specification must be precisely matched when selecting replacement wheels to guarantee compatibility and structural integrity.
Correctly identifying this specification is vital for several reasons. It ensures a secure and balanced connection between the wheel and the vehicle, preventing vibration, premature wear, and potential wheel detachment. Furthermore, adhering to the manufacturer’s specification maintains the vehicle’s intended handling characteristics and avoids compromising safety systems like ABS and stability control. Historically, standardization in this area has evolved alongside automotive engineering, with precise measurements becoming increasingly important for modern vehicle performance and safety.
