The wheels on the Civic Si are original equipment manufactured for Honda by an external wheel maker contracted by Honda; the exact supplier can vary by generation and market, but Honda oversees the design and approval process and the wheels typically bear either a Honda badge or the contractor’s branding on the rim.
How Honda sources the Civic Si wheels
Honda does not typically manufacture wheels in-house. Instead, their engineering team defines the wheel size, weight, offset, hub bore, load rating, and brake clearance. A recognized wheel manufacturer—an OEM partner contracted by Honda—produces the wheel to Honda’s specifications and ships it as part of the Civic Si’s equipment. The specific maker can vary by production run and market; Honda generally does not publish the exact supplier for consumers.
Design vs manufacturing roles
The wheel’s aesthetic and structural design are approved by Honda, with the actual forging or casting and finishing performed by the contracted supplier. The wheel is tested to meet safety and performance standards before it becomes part of the Civic Si lineup.
Variations by year and market
Wheels across the Civic Si lineup have evolved as the model has progressed through generations and across regions. The most recent US-market Si uses 18-inch alloy wheels with a distinctive finish, while some earlier versions used different sizes. The supplier identity may shift between generations; buyers should not assume the same maker across all years or regions.
Market differences
The US, Europe, and Asia sometimes receive slightly different wheel finishes or sizes, reflecting local regulations, manufacturing partners, and supply chains. If you need to know the exact maker for a specific VIN, the official Honda parts catalog or a dealership can confirm it.
How to verify the exact wheel maker for your vehicle
To identify the wheel designer or maker for a particular Civic Si, inspect the wheel for engravings and markings on the face or backside. Look for a brand name (the maker’s mark or a Honda badge), a part number, or a manufacturing code. Your Honda dealer or a VIN-based parts catalog can map that information to the supplier’s identity for that vehicle.
What to know if you’re replacing wheels
If you’re considering OEM replacement or aftermarket wheels, ensure compatibility with the Si’s specs: bolt pattern, center bore, offset, width, diameter, and load rating. Aftermarket wheels must respect Honda’s required clearance for brakes and suspension. While many aftermarket designs work, using wheels from the same OEM supplier can help maintain warranty and performance, though the exact maker will differ across model years.
Summary
In short, Honda designs and approves the Civic Si wheels while outsourcing their production to an external OEM partner. The precise maker can vary by generation and market, and wheel markings will indicate who produced the wheel for a given car. For exact identification, consult the VIN-based parts catalog or ask a Honda dealer.
