Construction options
Compare forged and cast proposals at the same size and load. Ask for actual part mass when weight matters and include tooling and sample costs.
Fitment and document review
HRE Wheels Fitment & Specs Desk
Use this checklist to turn a fitment request into a comparable supplier brief. Keep measurements, application data and target-market evidence tied to the same part revision.

- Finish, order quantity and port
Wheel and wheel-end RFQ worksheet
Send values and units in separate columns so suppliers can identify exceptions line by line.
| Review area | Buyer input | How to check |
|---|---|---|
| Wheel geometry | Diameter × rim width (in), bolt pattern / PCD (mm), signed offset ET (mm), center bore and hub pilot (mm), fastener seat and thread. | Reference wheel and dimensional drawing with revision. Treat 18 × 8.5 in, 5 × 114.3 and ET35 as sample notation only. |
| Clearance and finish | Brake package, spoke profile, barrel envelope, finish code and cosmetic acceptance zones. | Check the sample on the intended vehicle or against the buyer-approved caliper envelope. Confirm that the drawing matches the sample. |
| Load and inspection | Required load rating (kg per wheel), radial and lateral runout limits, mounting datum and inspection frequency. | Request the setup, measuring location and result for each sample. Keep measurement records separate from a structural performance report. |
| Commercial tires | Size designation, load index, speed rating, tread pattern, application and destination. | Compare tire options using the duty cycle and intended market; keep efficiency, wet grip and tread-life evidence tied to the quoted size. |
| Wheel-end assemblies and bearings | OE cross reference, vehicle or VIN as needed, hub flange, ABS encoder type, bearing bore / OD / width, preload, seal lip and included mounting hardware. | Match interfaces as well as numbers. On a serviceable bearing, agree how fit and preload will be checked; on an integrated hub, review the encoder and mounting flange. |
| Order scope | Quantity per SKU, target market, destination port, packaging and named Incoterm place. | Quote stock and custom lines separately. Ask whether tooling and validation sit inside the quoted schedule. |
Verify a quote against the part you will buy
Market and scope
If a supplier offers SAE J2530 or JWL/VIA evidence for a wheel, check the report or registration scope, market, part identification and dimensions.
System certificate
Check the issuer, validity period, site address and scope on any IATF 16949 or ISO 9001 certificate. Request SKU evidence separately.
Measurement record
Agree the datum, indicator location, conditions and limits with the buyer. Ask the inspector to record the sample ID and the high and low readings over one complete turn for each direction, then report the difference in mm. Request a separate report for structural validation.
Change control
Recheck the approved sample if the supplier changes the wheel width, offset or spoke profile. Log who approves the change and what must be measured again.
Missing evidence
Mark unmatched documents as open. Record the exact part, market and question to take to the supplier or qualified reviewer.
