Independent China sourcing · Alloy wheel desk
Ronal alloy wheel sourcing
Give suppliers one fitment brief so you can compare the wheels, sample requirements and trade terms on the same basis.
Submit a sourcing brief
Send the pitch circle diameter (PCD), wheel offset (ET), center bore, rim size, load rating and finish. Include the target market and vehicle or drawing reference.
Sourcing scope
Start with the wheel construction
Forged & Cast Alloy Wheels
Compare forging, casting and flow forming after setting the same rim diameter, rim width, mounting geometry and load rating. Ask each supplier whether tooling, coating and sample freight are separate quote lines.
View the alloy wheel catalog →Forged programs
Confirm material and temper, the mounting-face drawing and the sample approval plan.
Cast programs
Ask which molds cover your geometry and which finishes share a quoted minimum order quantity.
Flow-formed programs
Identify which part of the wheel is flow formed and request the report for the exact quoted configuration.
Quote intake
Inputs that change the quote
Fitment and finish
- Mounting
- PCD, ET, center bore, rim diameter and width, fastener seat and vehicle brake package.
- Acceptance
- Load rating, finish sample, and radial runout and lateral runout limits on the approved drawing.
Commercial scope
- Quantity and route
- Quantity per fitment and finish, target market, destination port and the named place in each quoted Incoterm.
- Evidence scope
- Supplier legal entity, site and exact wheel configuration covered by each document. Record any open gap before ordering.
Procurement sequence
Four decisions before dispatch
- 01
Freeze the brief
Separate buyer-approved dimensions from options suppliers may propose.
- 02
Compare offers
Line up unit price, tooling, minimum quantity, packaging and the named trade term.
- 03
Review a sample
Agree on drawing revision, sample checks and who signs off the result.
- 04
Clear the paperwork
Reconcile carton labels, quantities and packing list with the buyer’s forwarder.
Buyer routes
Match the brief to the order
Importers
Quote by market and destination port. Identify who checks import documents.
Distributors
Break out quantities by PCD, ET and finish to expose mixed-order constraints.
Fleet buyers
Pair the load rating with axle position, service duty and tire requirements.
Service networks
Use OE cross reference, hub flange and ABS encoder details for wheel-end briefs.
Catalog teams
Keep wheel geometry, finish approval and photo references tied to each SKU.

Questions before quoting
Where wheel briefs get stuck
Forged or cast?
Quote both on the same geometry and load rating. Forging may suit a project with a tight mass target, while a cast design from existing tooling may suit a lower tooling budget. Compare the supplier drawings, sample costs and test scope before deciding.
Can I start with just the diameter?
Yes, as an exploratory brief. A 17-inch diameter alone leaves width, PCD, ET, center bore, fastener seat and brake clearance open. Mark unknowns so quotes stay provisional.
Stock or a custom order?
An existing configuration can avoid new tooling if the supplier confirms the fitment and finish are available. A custom order can meet a specific drawing, with tooling, minimum quantity and validation quoted separately.
Can one report cover every finish or size?
Ask which configuration, revision and market the report lists. Send any mismatch in size, load rating or construction to the buyer’s quality reviewer before sign-off.
