Find Parts & Wheels That Fit Your Vehicle
Look up marketplace parts mapped to a model year, compare interchangeable catalog products, and check stored wheel size, offset, bolt pattern, center bore, and tire diameter. Shared catalog products are not a complete interchange verdict.

Check Wheel Fitment
Compare a stored reference wheel with a proposed diameter, width, offset, bolt pattern, bore, and tire size.
Parts Compatibility & Interchange
Marketplace products mapped to a model year, plus shared-product comparison between years of the same model.
Wheel Fitment & Size Comparison
Geometric position, bolt pattern, center bore, and tire diameter from stored configurations. Not a clearance verdict.
Wheel Fitment & Size Comparison
The checker compares one stored reference configuration with a proposed aftermarket wheel. It reports calculated geometry and independent checks. Brake, load, and body clearance stay unverified.
Choose a vehicle
- Wheel Size Comparison Diameter, width, and offset against the stored reference.
- Offset Calculator Inner- and outer-edge displacement from width and offset.
- Bolt Pattern Check Proposed bolt pattern versus the stored vehicle pattern.
- Center Bore & Hub Rings Wheel bore versus hub diameter, including ambiguous hub records.
- Tire Size Comparison Overall diameter difference when both ISO metric sizes are known.
- Wheel Hardware Rings, adapters, spacers, and lug hardware from the selected dimensions.
Calculation example
This is a geometry example, not a vehicle-specific fitment verdict. Original 8.0 × 18, ET40 versus proposed 9.0 × 18, ET30.
- Outer edge 22.7 mm farther toward fender (more outward poke)
- Inner edge 2.7 mm closer to suspension (less inner clearance)
What this catalog can tell you
- Marketplace parts mapped to a stored model year
- Public replacement categories, not Amazon ancestor folders
- Shared products between two years of the same model
- Stored wheel configurations and calculated wheel-position, bolt-pattern, bore, and tire-diameter change
What it cannot verify
Shared catalog products are not a complete interchange verdict. Brake clearance, load rating, and body or suspension clearance are not stored. A matching bolt pattern is not a complete fitment verdict.

Fitment terms
- Offset
- Distance from the rim centerline to the mounting face, in millimeters.
- Center bore
- The hole in the wheel. The vehicle hub is a different measurement.
- Stored configuration
- A catalog reference row. It is not automatically an OEM-approved factory wheel.
Questions
Can this checker say a wheel fits perfectly?
No. It reports independent checks. Brake, load, and body clearance stay unverified.
Does a matching bolt pattern mean the wheel fits?
No. Bolt pattern is one check. Bore, position, tire diameter, and clearance are separate.
What does a stored offset range mean?
It is the coverage in the catalog. It is not a safe band for every intermediate value.
