Tire Data APIs & Standards
Auto Care Association ACES/PIES Standards vs. Fitzy for Tire & Wheel Shops
The automotive aftermarket's standardized data exchange formats (ACES for fitment, PIES for product data), maintained by the Auto Care Association — an industry data standard, not a commercial storefront tool.
Auto Care Association ACES/PIES Standards is a real, legitimate tire data apis & standards provider — this page isn't claiming otherwise. It's not a full storefront, so the fair comparison isn't feature-for-feature; it's what you'd still need to build (or buy) around it to sell tires and wheels online, versus what Fitzy already includes in one platform.
| What It Takes | Fitzy | Auto Care Association ACES/PIES Standards |
|---|---|---|
| What it actually is | A complete ecommerce platform | A data feed / API / standard |
| Includes a customer-facing storefront | Yes | No — data only |
| Includes live, purchasable supplier inventory | Yes, 75+ suppliers | No — you'd still need to source and connect inventory separately |
| Includes checkout, financing, and fulfillment | Yes | No |
| Requires developer integration to use for ecommerce | No — ready to use | Typically yes |
| Ongoing engineering maintenance | Fully managed by Fitzy | Your responsibility |

Is Auto Care Association ACES/PIES Standards a competitor to Fitzy?
