Drill down into a generation: per-vehicle modifications with OEM specs and fitment deltas

Changed on

Given a specific generation from the by_rim/search/ hierarchy, returns individual trims/modifications with their OEM wheel specs and per-vehicle fitment data.

Each result includes the vehicle's OEM rim and tire specs, frontspace/backspace in mm, and deltas showing how much the searched rim differs from the OEM fitment. When cb (centre bore) is provided, cb_diff_mm shows the hub bore difference.

Request

Query parameters

bolt_patternstring required
Example:5x114.3

Bolt pattern is expressed as the number of lugs by the diameter of an imaginary circle formed by the centers of the wheel lugs. You can use GET /by_rim/bp/ to get a list of available value values. (e.g. 5x114.3)

rim_diameternumber double required
Example:18

Rim diameter is the distance measured in inches across the face of the wheel, from bead seat to bead seat. You can use GET /by_rim/rd/ to get a list of available value values. (e.g. 19)

rim_widthnumber double required
Example:7.5

Rim width is the distance measured in inches from bead seat to bead seat. You can use GET /by_rim/rw/ to get a list of available value values. (e.g. 7.5)

rim_offsetnumber double required
Example:35

Rim offset is a distance between wheel mounting surface where it is bolted to hub and the centerline of rim. You can use GET /by_rim/of/ to get a list of available value values. (e.g. 38)

cbnumber double

Centre bore value, mm (e.g. 60)

fdnumber double

The fd parameter represents the diameter of the wheel fastener threads, measured in millimeters (mm). This parameter is essential for ensuring a secure fit of the wheel's bolts or lug nuts. For a list of possible values and additional details, please refer to the Thread Size ISO and UN Series Glossary on Wheel-Size.com. (e.g. 14)

fs_pokeinteger

Frontspace poke tolerance in mm. 0 = exact or safer only (no poke). Default: 2. (e.g. 2)

bs_pushinteger

Backspace push tolerance in mm. 0 = exact or safer only (no push). Default: 2. (e.g. 2)

rim_bst_frominteger

[Deprecated] Mapped to bs_push. Use bs_push instead.

rim_bst_tointeger

[Deprecated] Safe direction is now uncapped. Mapped to bs_push if sent alone. Use fs_poke/bs_push instead.

od_tolerancenumber double

Percentage adjustment for the overall diameter tolerance range (0–5%), where default is 1%.

ow_tolerancenumber double

Percentage adjustment for the overall width tolerance range (0–3%), where default is 0%.

diameter_rangeinteger

Widen rim diameter search window by ±N inches. 0 = exact match only. Default: 0.

sort'name' | 'fitment' | 'load'

Sort order: name (A-Z), fitment (closest FS delta), load (heaviest first).

makestring required
Example:mitsubishi

A car's Make is the brand of the vehicle. You can use GET /makes/ to get a list of available slug values. (e.g. mitsubishi)

modelstring required
Example:outlander

The particular Model of the brand. You can use GET /models/ to get a list of available slug values. (e.g. outlander)

generationstring required
Example:a65f0f2858

Vehicle Generation refers to the life cycle of a design for a specific make and model. You can use GET /generations/ to get a list of available slug values. (e.g. 18d10dc6e6)

limitinteger

Maximum number of items to return (default 100, max 1000).

offsetinteger

Number of items to skip before collecting the result set.
