Open Wheel Fitment Dataset: Bolt Pattern & Centre Bore Data

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 10,093 vehicle variants across 174 makes and 56 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.

API

The current release can also be fetched directly over HTTPS. No API key or sign-up is needed, and CORS is enabled (Access-Control-Allow-Origin: *), so the endpoints work from browser JavaScript as well as from servers.

• GET https://ankusiwheels.com/wp-json/ankusi/v1/dataset/csv — the full table as UTF-8 CSV, one row per vehicle variant.
• GET https://ankusiwheels.com/wp-json/ankusi/v1/dataset/json — the same rows as JSON, with name, version, license, records, columns and data (the rows) fields.

Both endpoints return the whole dataset in one response (there is no paging or filtering), so cache the file rather than requesting it on every page view. Columns are described below. Please credit the source as set out under Licence and attribution.

To query by make, model, year or bolt pattern instead of downloading everything, use the Wheel Fitment API. To check a wheel size against a vehicle without writing code, use the Will It Fit? wheel fitment checker, which runs on this dataset.

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, an IATF 16949 and ISO 9001 certified forged wheel manufacturer in Guangzhou, China. 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.

Mirrors

Version 2026.10.13.1

Point release. Centre bore corrections confirmed by two independent references: Tenet A8 60.1 to 65.1 mm (wheel-size.com and its Chery Arrizo 8 donor on avtoreference.com); Belgee X80 PHEV 63.4 to 54.1 mm (wheel-size.com and the Geely GEA platform EX5 on avtoreference.com); Livan X6 Pro 60 to 60.1 mm. OE offsets corrected for the Solaris HS and KRS (ET52 to ET49) and Solaris HC (ET45 to ET43). Added GAC Emzoom (2025). 10,081 rows, 174 makes.

Version 2026.10.13

34 vehicles added, mostly Russian-market and Chinese models published on the English site for the first time (Tenet T4/T7, Belgee X50/X70/S50, Moskvich 3/6/8, Evolute i-JOY/i-SKY/i-SPACE, FAW Bestune T55/T77, Changan UNI-S/Lamore, JAC S3 Pro/J7, WEY 05, Chery Tiggo 7L/Arrizo 6 Pro, NIO ET5T, Omoda S5, Kaiyi E5/X3, Knewstar 001, Sollers ST6, Zeekr 001 and others); each has bolt pattern, centre bore and factory wheel size matching between two independent references. 24 language-site rows for the same car and year were replaced by the new English rows. Centre bore corrections confirmed by a third reference (wheel-size.com): Denza D9 64.1 to 63.4 mm; Tenet T8 60.1 to 65.1 mm. BYD Atto 3 / Yuan Plus centre bore is withheld in this release because references disagree (60.1 mm vs 64.1 mm). 10,080 rows, 174 makes.

Version 2026.10.04

Make names normalised: 29 records listed under "Seat" now use "SEAT" and 6 records listed under "Great-wall-gwm" now use "GWM", so each manufacturer appears under one spelling. No fitment values changed. 9,701 rows, 169 makes (previously counted as 171).

Version 2026.09.20

Consistency pass over the full dataset (flush/maximum offset logic, model-year ranges, factory wheel sizes cross-checked against wheel-size.com and avtoreference.com) plus resolution of the 13 withheld centre bores and the 21 single-source Buick records. 20 factory wheel-size records corrected (offsets that had been copied from a sibling model or mistyped); 7 model-year ranges corrected; 4 records had their flush and maximum references listed in the wrong order and were swapped; 13 centre bores reinstated (Buick Cascada 70.3 mm confirmed by wheel-size.com and wheel-sizes.com; Geely Vision FC2/FC3 60.1 mm - the earlier conflict was an automated lookup matching the wrong Geely model); 20 Buick records added after a second reference was found (Rendezvous 2002-2007 via wheel-sizes.com, Velite 5/6/7 via wheel-size.com). The aftermarket flush/maximum references on the 20 offset-corrected records were written against the old figure and are blank in this release pending re-verification. 7,583 to 7,603 rows.

Version 2026.09.19b

Expansion: 1,156 additional vehicle variants (Buick 462, Geely 415, Porsche 332 incl. classic 356/914/924/928/944/968 and current 911/718/Cayenne/Macan/Panamera, Rolls-Royce 69, Lamborghini 10) added after the same two-source verification (wheel-size.com + avtoreference.com; 999 variants confirmed by both, the remainder by one source plus a sibling-generation match on the other). 7 Porsche Macan Electric records (2025-2026) corrected from 5x112 to 5x130 before inclusion. Centre bore withheld pending verification on 13 records (Buick Cascada 2016-2019: 70.3 vs 70.2 conflict; Geely Vision FC2/FC3 2014-2022: single source). 29 pages not included: 21 single-source records (Buick Rendezvous, Velite 5/6/7) and 8 competition/bespoke variants.

Centre bore withheld pending verification: Buick Cascada 2016-2019; Geely Vision FC2 2014-2018; Geely Vision FC3 2019-2022.

Version 2026.09.19

Anomaly audit of 190 flagged records (39 rare bolt-pattern/centre-bore combinations, 166 brand outliers, 12 blank centre bores) re-verified against wheel-size.com, wheelfitment.eu, wheel-sizes.com, avtoreference.com and marque forums. 9 records corrected, 9 staggered hub bores now exported with a new center_bore_rear_mm column, 8 unconfirmed centre bores blanked, 9 records withdrawn pending verification.

Centre bore withheld pending verification: Ford E-Series 2008; Hummer Humvee 2003; Lamborghini Jalpa 1981; Lamborghini Temerario 2025; Lamborghini Temerario Ad Personam 2026; Lotus Esprit V8 2002; Oldsmobile Cutlass 1961; Porsche 914-4 1970.

Version 2026.09.18

Initial public release, 6,436 records.

Version 2026.10.10

Expansion: 369 vehicle variants added across 47 makes after two-source verification (avtoreference.com + tirewheelguide.com, or tirewheelguide.com + wheel-size.com read in-browser; bolt pattern and centre bore must agree on both). Focus of this release: Volkswagen (Arteon, Teramont, T-Cross, Taos, Taigun, ID. Buzz, Amarok I/II, Scirocco, Beetle, Transporter T5-T7, Multivan, Caddy, Touran, Sharan, CC, Virtus, Nivus, Lamando, Sagitar, Magotan, Bora (CN), Lavida, Phaeton, Up, Vento (IN)), Lynk & Co 02/03/05/06/08/09/900/Z10, Proton Saga/X70/X50/Persona, Suzuki Baleno/SX4/Fronx/Grand Vitara, Toyota Harrier/Aristo/Land Cruiser 70, Renault Trafic/Master, Ram 3500/ProMaster/Rampage, Pontiac, Saturn, Mahindra XUV300/XUV 3XO, Rivian R1S, VinFast VF8/VF9, Polestar 3, Maybach S-Class/GLS, Ferrari F12, Daewoo, Plymouth Prowler/Neon, Lada 4x4, and several Chinese makes (XPeng G7, Xiaomi YU7, NIO ES8/ES7, IM LS6, Deepal L07, Hongqi HQ9, Ora 07, BAIC BJ60/BJ80, iCar V23, Forthing, JAC T8/T9, Borgward, HiPhi Z). Where a model carries a different bolt pattern in another market the market is suffixed in the model name ((CN), (IN), (JP)). Aftermarket flush/max columns are left blank for every new record: no verified aftermarket figures exist yet, and the dataset never guesses them. Correction (same day): 157 max_wheel values whose negative offset had been cut to a bare "ET" by the export (e.g. Brabus Crawler 20x11.0J ET-20, BMW 3.0 CSL E9 rear ET-5) now carry the full figure.

Version 2026.10.16.4

Correction: centre bore for the Toyota TNGA-F platform (Land Cruiser 300, Land Cruiser 250 / Prado 250, Lexus LX 2022+) changed from 95.1 mm to 95.2 mm on 16 records, after wheel-size.com and avtoreference.com both listed 95.2 mm.

Version 2026.10.19

New-model release: 12 vehicles added after two-source checks (wheel-size.com plus avtoreference.com, threepiece.us or a factory-wheel stamp): Honda Passport (2026), Honda Prelude (2026), Honda HR-V (2025), Toyota C-HR EV (2026), Rivian R2, Acura ADX, Jeep Cherokee KM (2026), Volkswagen Jetta and Jetta GLI (2025), Geely EX5, BYD Sealion 7 and BYD Atto 2. Centre bore is left blank for Jeep Cherokee (sources give 71.5 and 71.6 mm) and BYD Atto 2 (only one source), and flush/max columns are blank for all new records. Correction: Tesla Model 3 Highland factory wheel offset changed from ET40 to ET38 on 3 records. 10093 rows.
