PCD, ET and center bore are the three fields that stop a forged sample from becoming a return. How importers lock them before MOQ 4.
A forged sample that does not sit on the hub is a wasted 15-day path. Before XBORUL cuts a MOQ 4 evaluation set, we lock three numbers: PCD (bolt pattern), ET (offset) and CB (center bore). Vehicle photos help. Guessing from a competitor listing does not.
Direct answer
Send vehicle year/model or the three numbers. We confirm a manufacturable PCD / ET / CB, then sample. Do not order bulk from a spacer-dependent retail listing.
PCD โ bolt pattern
PCD is how many lugs and the circle they sit on, e.g. 5×112, 6×139.7, 8×170. Common classes we quote:
- 5×112 โ many BMW and Mercedes performance programs. See BMW forged and Mercedes forged.
- 5×5 / 5×5.5 class โ Jeep Wrangler beadlock and trail catalogs. See Jeep beadlock.
- 6×139.7 โ Tacoma / 4Runner / many mid-size truck and SUV programs. See Toyota forged.
- 8-lug HD โ F-150 class and super single. See F-150 truck wheels.
Always confirm the generation. Two trucks with the same badge can ship different patterns.
Offset (ET)
ET sets how far the face sits in or out of the arch. Stance catalogs run more aggressive ET than OEM-plus. Share:
- Target tire size and whether the truck is lifted
- A photo of a wheel that already fits, with size stamped on the inner rim
- Caliper clearance notes if you run big brakes
Center bore (CB)
Hub-centric fitment starts with CB. Rings can fill a larger bore down to a hub; they cannot invent a smaller bore. We lock CB with PCD so the sample is hub-centric for the stated platform โ not โclose enough with spacers.โ
Minimum RFQ that actually quotes
- Vehicle list or PCD + ET + CB
- Diameter ร width
- Quantity (sample 4 vs batch)
- Finish and destination market
Example that works: โ20ร9 / 20ร10.5, 5×112, ET 25 / 32, CB to confirm, gloss black, 4 pcs sample then 40, EU.โ Open that on Contact or start from the fitment hub.
