Offroad Source: Wheel & Tire Package Builder for BigCommerce

The Problem: No Fitment Verification for High-Value Wheel & Tire Purchases
Offroad Source sells high-value wheel and tire packages to off-road enthusiasts. The average order is between $3,800 and $5,200. At that price point, a customer does not guess they need to know the wheels fit their specific vehicle, the tires match the wheel size, and the complete package is correct before they commit.
BigCommerce’s default product structure treats wheels and tires as separate products on separate pages. A customer trying to build a compatible set had to find a wheel, check its bolt pattern and offset against their vehicle’s specifications, navigate to the tires category, find a tire in the right diameter to match the wheel, verify the load rating, add both to cart individually, and hope they had not missed anything. That process unclear, unguided, and entirely the customer’s responsibility to verify was generating confusion, incorrect purchases, and lost sales on orders worth thousands of dollars.
There was no fitment verification tool. There was no way to browse packages by vehicle. There was no single page showing wheel and tire specifications side by side with a confirmed price. The store’s catalogue was technically complete but commercially broken for how its customers actually needed to shop.

The Solution: A Guided Package Builder From Product Page to Cart
Codinative built a fully custom wheel and tire package builder on BigCommerce Stencil four interconnected components that take a customer from product page entry point to a confirmed bundle in the cart in one guided flow.
A Build Your Wheel & Tire Set CTA on the product page launches the builder. A package browsing interface with vehicle fitment dropdowns Year, Make, Model, Submodel, Chassis and tire dimension filters narrows the catalogue to compatible packages. Package listing cards show the wheel and tire preview images, total package price, and confirmed inclusions at a glance. A Package Details page surfaces full wheel specifications and full tire specifications side by side, optional add-ons, and a Buy Now button that submits the complete bundle four wheels and four tires to the BigCommerce Storefront Cart API in one action.

Offroad Source Wheel & Tire Package Builder FAQ's
What is a wheel and tire package builder on BigCommerce?
A wheel and tire package builder is a custom purchasing flow built on BigCommerce Stencil that lets customers select a compatible wheel and tire combination for their specific vehicle and add the complete set four wheels and four tires to cart in one action. It replaces the default separate-product browsing experience with a guided flow that includes vehicle fitment verification, tire dimension filtering, side-by-side specifications, and confirmed package pricing before purchase.
How does the vehicle fitment filtering work?
The vehicle fitment system uses cascading dropdowns Year, Make, Model, Submodel, Chassis. Each selection fires a JavaScript filter that eliminates incompatible packages from the results. Make only activates after Year is selected, Model only after Make, and so on. When all five fields are populated and the customer clicks Go, the package results update to show only wheel and tire combinations where the bolt pattern, offset, and hub bore are confirmed correct for that vehicle.
How does the package builder add a complete set to the BigCommerce cart?
When the customer clicks Buy Now on the Package Details page, JavaScript collects the selected wheel's variant ID and the selected tire's variant ID, sets quantity to 4 for each, and submits them to the BigCommerce Storefront Cart API. The API call uses a lineItems array with two entries one for the wheel at quantity 4 and one for the tire at quantity 4. Both line items land in the cart in one network request. The customer does not add wheels and tires separately.
What are the optional add-ons on the Package Details page?
Four optional add-ons are available as dropdowns: Add a Matching Spare (a fifth wheel and tire for the spare position), Add a TPMS (Tire Pressure Monitoring System sensors), Add a Lug Kit (matching lug nuts for the selected wheel's bolt pattern), and Add a Lug Wrench. Each add-on has a help icon that explains what it is. Selected add-ons are included in the Buy Now submission alongside the main wheel and tire line items.
Why does the cart show both wheel and tire as separate line items?
The BigCommerce cart stores products as individual line items. The package builder adds four wheels and four tires as two separate line items rather than a single bundled SKU, which preserves BigCommerce's native inventory management, return processing, and order management for both products independently. The cart page is styled to display both line items together with brand, full product name, SKU, quantity of 4, and line total so the customer immediately reads it as a complete set.
Can the vehicle fitment data be maintained without developer involvement?
Yes. Vehicle fitment data is managed through BigCommerce custom fields on each wheel and tire product. Adding a new vehicle fitment or a new package requires updating the relevant custom fields in the BigCommerce admin. No code changes are required. Offroad Source's team can manage their fitment catalogue directly from the BigCommerce admin without contacting a developer.
Does the builder work for different wheel sizes and tire brands?
Yes. The tire dimension filters Width/Height, Aspect/Width, Rim Size and the Brand checkboxes in the Shop Tires panel filter the package catalogue dynamically. The brand list includes AMP Tires, Atturo Tire, BFGoodrich, Cooper, Falken, Fuel, Fury, General, and Gladiator. Each filter updates the results count live. Customers who want a specific brand or a specific tire dimension filter down from 317 results to the exact packages that match their requirements.
How long does it take Codinative to build a custom wheel and tire package builder?
A package builder of this scope vehicle fitment dropdowns, tire dimension filters, package listing cards with live pricing, a Package Details page with side-by-side specifications and add-on dropdowns, and Storefront Cart API bundle submission takes Codinative six to ten weeks from discovery to live deployment depending on the size of the vehicle fitment database and the number of package combinations in the catalogue.
