The ANKUSI Wheel Fitment Dataset is an open, machine-readable table of factory wheel specifications — bolt pattern, centre bore, lug count and OE wheel size — for 6,436 vehicle variants across 129 makes and 46 bolt patterns, model years 1940–2027. It is released under CC BY 4.0: free to use, copy, adapt and build on, including commercially, as long as you credit the source.

How the data is compiled
Records are built from published OEM wheel and tyre specifications and cross-checked against independent fitment references before publication; where two sources disagree the record is held back rather than guessed. Aftermarket flush and maximum figures are reference starting points collected from documented builds on each platform, not manufacturer approvals — clearance always has to be verified on the individual car, because brake package, suspension, tyre profile and ride height all change the outcome.
Compiled and maintained by the engineering team at ANKUSI Wheels. ANKUSI is the brand and export arm; the wheels are produced at Taizhou Hantuo Automotive Parts Co., Ltd (Jiangsu, China), which holds IATF 16949:2016 (TÜV Saarland, certificate CB01839, IATF registration 0572069) and ISO 9001:2015, scope “design and manufacture of wheel hubs, with product design responsibility”. We publish it because we need the data accurate for our own production, and an open version is more useful to everyone than another paywalled lookup.

Corrections
If you find a record that does not match a factory placard or service manual, send the vehicle, the year and your source to our engineering team and we will re-verify it. Corrections are applied to the dataset and to the underlying fitment guide.
