Rotiform Alloy Wheel Procurement
Turn a fitment sheet into a shortlist you can compare, sample and verify before placing a wholesale order.
Three routes to an alloy wheel brief
Choose the construction route you want to compare.
Forged alloy wheels
Compare an offered forging by drawing revision, brake envelope and sample scope.
ET · brake envelope · drawing

Flow-formed alloy wheels
Ask for the barrel process and evidence tied to the finished wheel configuration.
Barrel process · runout · test scope

Compare both on the same rim diameter, width, pitch circle diameter (PCD), offset (ET), center bore, finish and load rating.
| Request line | Cast catalog route | Forged custom route |
|---|---|---|
| Drawing | Ask which existing design covers the required ET and brake envelope. | Ask which dimensions require a drawing revision. |
| Sample | Confirm the sample carries the same model, size and finish as the quoted line. | Confirm the sample uses the agreed drawing and quote the cost of revisions separately. |
| Evidence | Request model-specific load and runout documentation. | Request the same evidence for the proposed configuration. A material grade describes the alloy and temper. |
| Commercial scope | Check the MOQ by diameter and finish, and clarify available quantities in writing. | Separate sample, tooling and unit prices. Confirm the lead-time trigger in the supplier quote. |
Follow the brief from request to dispatch
- 01
Describe the vehicle
Record model year, trim, axle and brake package before mapping the wheel envelope.
- 02
Align the bid lines
Use a common drawing revision, unit, currency, Incoterm and destination to compare supplier quotations.
- 03
Agree the evidence
Confirm sample identity and how an independent inspector would measure lateral and radial runout.
- 04
Confirm the handoff
Reconcile SKU, finish, carton labels and quantities across the packing list and buyer-approved order.
Evidence before commitment
Identify who supplies each record and who makes the release decision.
Supplier record
Supplier-provided. Identify the legal entity and site on the quote.
Sample identity
Supplier-provided. Match part markings, dimensions and finish to the drawing revision.
Document scope
Supplier-provided. Match any test report to the model, size, load and target market.
Inspection brief
Third-party. Define the checkpoints, instruments, lot and acceptance basis before inspection.
Sample decision
Buyer-approved. Record axle, vehicle and the sample version covered by the decision.
Shipment handoff
Buyer-approved. Reconcile carton markings, ordered units and the forwarder handoff point.
Wheel sourcing questions
It defines the bolt count and pitch circle diameter in millimeters. Add rim diameter and width, wheel offset, center bore, seat type, brake package, axle load and finish before sending it as a fitment request.
A catalog offer can use an existing drawing if the size and finish fit the brief. A custom offer can prioritize an offset or finish outside the catalog, with drawing and sample milestones. Compare quantities, Incoterms and evidence on the same basis.
The buyer defines the application criteria and decides on the sample. The supplier provides product records and a third party can inspect against an agreed checklist. Rotiform coordinates those inputs.
Bring the fitment notes you already have
An OE reference, drawing revision or vehicle and brake package is enough to begin identifying the missing inputs.
