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

Changed on

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

Each result describes the vehicle's OEM wheel pair closest to the searched tire: its rim and tire specs plus deltas showing how much the searched tire differs from it: ow_delta_mm (overall width), od_delta_mm and od_delta_percent (overall diameter), and ar_delta (aspect ratio, percentage points). load_kg / load_index are the maximum over all of the vehicle's matching pairs.

Matching is identical to by_tire/search/ — exact rim diameter, with tire overall width and overall diameter within ±2 mm — so against the same data every generation returned by the parent endpoint resolves here to at least one modification. The two responses are cached independently, so right after a catalogue update an empty result is possible. The ±2 mm window also bounds ow_delta_mm and od_delta_mm to ±2: they report how exact the match is, not a size change.

There is no cb_diff_mm here — a tire has no centre bore.

Request

Query parameters

section_widthinteger required
Example:235

Section width is the width of the tire in mm. You can use GET /by_tire/sw/ to get a list of available value values. (e.g. 225)

aspect_ratiointeger required
Example:60

The Aspect ratio is indicated on the tire sidewall as a percentage. It's the height of the sidewall measured from wheel rim to top of the tread, expressed as a percentage of tire width. You can use GET /by_tire/ar to get a list of available value values. (e.g. 45)

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)

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.
