Use the calculator below to compare wheels from another vehicle against your 2003 Infiniti Q45, or check compatible donor vehicles that share the same bolt pattern and center bore.

Fitment Basics

  • Always confirm center bore matches your hub, or use hub-centric rings to take up the gap.
  • Check offset carefully – wheels that stick out too far can rub on fenders or suspension components.
  • Verify thread size and lug type before buying replacement bolts or lug nuts.
  • When in doubt, use the calculator below to compare exact specs side by side.

Methodology and sources

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:

  • Bolt pattern / PCD
  • Center bore direction (donor wheel bore must not be smaller than the hub)
  • Wheel diameter, width, and offset against known OEM ranges
  • Lug thread / hardware differences (vehicle-side hardware)

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.
