list-classified-rims
List aftermarket rim products compatible with a given rim fitment spec. Required: bolt_pattern, rim_diameter (inches), rim_width (inches), rim_offset (ET mm). Optional: cb, fd, fitment tolerances (fs_poke, bs_push, od_tolerance, ow_tolerance), diameter_range, sort, limit, offset. Returns rim produc…
list-generations
List all body generations for a given make/model/year combination. Returns generation slugs (e.g., "b9" for Audi A4 2020) used as the "generation" input for list-modifications and classified tools.
list-hf-tire-overall-diameters
List all overall diameter values (inches) for high-flotation (HF) tyres, optionally filtered by region. HF tyres use the imperial size format: OD x SW R RD (e.g. 33x12.5R15). Common on pickup trucks and off-road vehicles. Use this to discover valid overall_diameter values for search-by-hf-tire.
list-hf-tire-rim-diameters
List all rim diameters (inches) available for HF tyres, optionally filtered by overall diameter and section width. Use this to discover valid rim_diameter values for search-by-hf-tire.
list-hf-tire-section-widths
List all section widths (in inches) for HF tyres, optionally filtered by overall diameter and region. Note: section_width is in INCHES for HF tyres (e.g. 12.5), unlike standard tyre tools where it is in mm.
list-makes
List all vehicle manufacturers (makes) available in a given market region. Returns slugs used as the "make" input for subsequent tools. Make availability is region-dependent, the same brand may have different slugs across markets.
list-models
List all vehicle models for a given make and year. Returns slugs used as the "model" input for list-generations, list-modifications, and search-by-model.
list-modifications
List all trim/engine modifications for a given make/model/year/generation. Useful for drilling into specific engine variants before querying fitment data.
list-regions
List all available market region codes (e.g., "eudm" for Europe, "usdm" for North America, "jdm" for Japan). Region codes are required inputs for list-makes, search-by-model, and wheel-upsteps. Start here when region is unknown.
list-rim-bolt-patterns
List all bolt patterns (PCD) available in the database, optionally filtered by rim dimensions and centre bore range. Bolt pattern format: stud-count × circle-diameter in mm (e.g. "5x112"). Use this to discover valid bolt_pattern values before calling search-by-rim.
list-rim-centre-bores
List all centre bore (CB) values available, optionally filtered by rim dimensions, offset range, and bolt pattern. Centre bore is the diameter of the hole in the wheel centre in mm (e.g. 66.5). Use this to discover valid cb values for search-by-rim.
list-rim-diameters
List all rim diameters (in inches) available in the database, optionally filtered by bolt pattern and region. Use this to discover valid rim_diameter values before calling search-by-rim.
