Buyer applications

Continental sourcing by operating duty

A distributor's size mix and a fleet's axle schedule need different sourcing briefs. Start with the job the tire or wheel end must do, then specify how to check the offer.

Choose the brief that matches your order

01 / Catalog planning

Importers and distributors

For a mixed-size passenger program, send the size matrix, load index, speed rating, tread pattern and target market. Keep replacement demand separate from special-order lines. A stock program can simplify replenishment when the supplier confirms SKU and lot availability. Custom lines may fit narrower labeling or casing needs and need separate sample approval.

Review: if the brief contains 225/45R18 95W, compare the full line against the sidewall photo and packing label before building the mixed-container loading plan.

02 / Route and axle

Commercial fleets

Separate steer, drive and trailer duty and provide the target vehicle load, inflation basis and axle position. A lower rolling resistance tire may suit longer steady routes. A wet or abrasive duty cycle also calls for a grip and wear review. Ask suppliers to explain the measurement method, load, pressure and comparable test configuration.

Review: record rim width and rim diameter from the vehicle specification and check single and dual load ratings when applicable.

03 / Wheel-end interfaces

Service networks and OEM projects

Record the OE cross reference, vehicle or VIN reference where appropriate, hub flange dimensions, ABS encoder ring orientation and wheel speed sensor interface. An integrated hub unit reduces field assembly steps. A serviceable bearing is an option where the platform permits it and the installer can control bearing preload and seal lip installation.

Review: compare drawings and sample interfaces. For wheels, capture bolt pattern, pitch circle diameter (PCD), wheel offset (ET), center bore and load rating.

04 / Terrain and casing

Agricultural and off-road duty

Identify surface, axle load, sustained speed, operating pressure and expected cut exposure. Compare a road-oriented pattern with a deeper-lug option against the working surface and duty cycle. Share rim diameter, rim width, casing construction and the load table needed for the application.

Review: request a comparable load and speed basis before evaluating the tread pattern, tread depth and packing implications.

Buyer checklist

Mark what is ready to send

Keep any open points in the brief so suppliers can identify assumptions in their responses.
