Tire Size API

Fast, edge-served OEM and alternate tire-size reference data by vehicle. Browse makes and models, look up the fitment for a specific vehicle with /by-vehicle, or search by make, model, year, tire size or free text. Each record carries year, make, model, trim/submodel, the OEM tire size and any alternate sizes.

Coverage: ~580 vehicle fitments across 36 makes, model years 1989–2025 (sample dataset). Search requires a narrowing query (a model, a tire size, a 3+ character q, or at least two filters); list endpoints return up to 25 rows per call.
