Wheel Configurator API — Frequently asked questions

The Wheel Configurator API is a visualisation tool that lets you show wheel and tire upgrades on real vehicles. It can be integrated into any website or application to enrich product pages and drive conversions.

It combines our fitment database with a neural image-composition pipeline. A caller selects a vehicle and submits a rim image; the API returns a high-resolution composite showing the rim fitted to that specific vehicle.

Each Configurator subscription covers a single website or application. If you need it on two websites, you need two subscriptions — and so on. See the full Configurator terms.

EVOX Images® is a leading provider of high-quality automotive imagery with a focus on VR and 360° content. We use their imagery because it offers the most comprehensive, consistent and high-quality vehicle database — ensuring a true-to-life visualisation through the Configurator.

No. The EVOX logo represents our partnership with EVOX and is a requirement of our licensing agreement. It is placed subtly in the bottom-right corner of every image and cannot be removed, covered or altered — see EVOX logo terms.

U.S. and Canadian vehicle applications since 2004, EU vehicle applications since 2019. The imagery is updated daily from EVOX.

You can use it for e-commerce — most commonly, enriching product description pages on retail sites that sell car rims.

We have a formal partnership with EVOX that authorises us to redistribute their high-quality vehicle imagery through the Wheel Configurator API. Every image you receive is served under that agreement, so the content is fully authorised and authentic.

Per the EVOX agreement we share monthly usage data — the list of URLs and mobile applications where the Configurator API is deployed — to ensure compliance and accurate tracking of API usage.

No. The Wheel Configurator API is a complement to the Wheel Fitment API and is available only to subscribers of the Business plan or higher. Active subscribers are eligible immediately; see the pricing & payment page.

For best composite results, adhere to these guidelines for every rim image you upload:

1. 1. Orientation: the rim should be turned slightly to the side so it overlays naturally on the vehicle-image perspective.

2. 2. File size: the image must not exceed 1 MB. Smaller files process faster.

3. 3. Dimensions: not larger than 2000 × 2000 px; not smaller than 250 × 250 px.

4. 4. Background: any background works, but a transparent background integrates more cleanly and processes faster.

Email info@wheel-size.com with the specific vehicle and we will do our best to add it.

Our imagery combines two sources:

Combining both lets us cover the broadest possible vehicle catalogue.

Our Configurator API has broad global coverage with the deepest catalogue in key automotive markets:

The catalogue expands continuously as we add coverage for new models and regions.

Three techniques improve composite-generation speed:

1. 1.Submit rim images on a transparent background. This skips the background-clearing step, which otherwise takes real neural-network time.
2. 2.Aim for rim files of 150 – 500 KB. The sweet spot for fast uploads and minimal processing.
3. 3.Our neural network only performs an initial check on each rim image. Subsequent uses of the same image skip most of that work, so the first composite for a rim takes about twice as long as later composites for the same rim.

Full terms live on the Terms of Usage page. The three key points:

• The EVOX logo must remain on every image — it signifies our partnership with EVOX.
• Every API call must be initiated by a real user (site visitor, application user). No search robots, crawlers, spiders or parsing scripts.
• Each subscription covers one website or application. Additional platforms each require a separate subscription.
