Potential requirementWheel spacer ≈ 5.18 mm
Hub-centric rings required: 100.3 → 78.3 mm mm. Wheel geometry also suggests a spacer of about 5.18 mm; verify clearance. Use lug nuts / bolts specified for your vehicle.
Donor width/offset sits outside the known OEM envelope for this vehicle. Precomputed data suggested a spacer; geometry was re-checked against OEM envelope. Use lug nuts / bolts specified for your vehicle.

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares:
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
