A free JSON API that returns wheel fitment data — bolt pattern, center bore, factory wheel size and offsets, plus reference flush and maximum aftermarket sizes for vehicles. Covers about 10,070 vehicles and requires no API key.
Build a fitment lookup for a parts store, add vehicle compatibility filters to classifieds, or make a ‘will it fit’ wheel checker. The API gives bolt pattern, center bore, OE and reference aftermarket sizes, and you can download the full dataset as JSON or CSV. It’s keyless and CORS-enabled so you can prototype quickly in the browser. Results are cached for an hour, so cache locally and avoid high-frequency polling.
