The configuration describes the arrangement of the lug nuts or bolts that secure a wheel to a vehicle’s hub. For the specified truck model and year, this measurement is 5×139.7mm (or 5×5.5 inches). This designation indicates a five-lug design, where the lugs are positioned on a circle with a diameter of 139.7 millimeters (5.5 inches). Selecting wheels with the correct arrangement is crucial for safe and proper installation.
Proper wheel fitment is paramount to vehicle safety and performance. Utilizing wheels with the incorrect specification can result in wheel instability, potential damage to the vehicle’s wheel bearings and studs, and ultimately, wheel separation. Historically, these dimensions have been standardized across various vehicle manufacturers to simplify wheel interchangeability within specific vehicle classes. Knowing this dimension ensures compatibility when replacing wheels or upgrading to aftermarket options.
