Selling tires and wheels online is a fitment problem before it is a price problem. A shopper who isn't sure a 225/45R17 will clear their fender, or whether a wheel's offset and bolt pattern match their vehicle, abandons the cart. The Tire & Wheel Size Finder removes that doubt by matching your live Shopify catalog to a vehicle's exact specifications.

This is not an instant App Store download. ECOSIRE builds, installs and configures the finder for your store, your theme and your product data — then supports it. We deliver it as an embedded Shopify app using OAuth install, the Admin GraphQL API, and product metafields to store fitment attributes (tire size, rim diameter, offset, bolt pattern, OEM and plus-size data, TPMS flag) against your variants. The mobile-first finder widget is injected through a theme app extension so it works with Online Store 2.0 themes without hard-coding.

Shoppers can search by tire size or drill down by vehicle (year / make / model / trim) and instantly see only products that genuinely fit — including plus-size and staggered setups and a visual fitment confirmation badge on the product page. Your team manages thousands of fitment records via bulk import, and product or inventory changes stay in sync through Admin API webhooks and multi-location inventory.

Because it's built to order, the spec sheet, vehicle database, and matching logic are tailored to how you sell — not forced into a generic template. We scope the build with you, deliver in a defined lead time, and hand over documentation. Honest, custom, and supported — that's the difference.
