Manufacturers → models → body types → engines → fitments. ISO-metric sizes. No scraping, no cleanup.
Every fitment passes ETRTO geometry + load-index checks; suspect rows quarantined, not shipped.
JSON API + an MCP server so AI assistants answer "what fits my car?" from a source they can trust.
New model years every quarter. API & SQLite subscribers update automatically.
Wheels Easy fitment data starts at €299/year for the full dataset (CSV/SQLite) or via the REST API. That compares with TecDoc/TecAlliance licences that typically run into five figures per year, and Wheel-Size API plans around $800/year per property. Prices verified 2026-06.
Validated. Every record passes physics checks (ETRTO geometry and load-index floors) and carries provenance; rows that fail are quarantined rather than shipped. This is what makes it warrantable for resale and safe for AI agents.
Yes — there is a JSON REST API and an MCP server so assistants like Claude can call fitment lookups as native tools. See the agents page.
