Specification Center / Dimensions, loads and evidence
Turn a size reference into a supplier question with the rim, application and exact-part load evidence attached. Keep the buyer's required values separate from the supplier's proposal.
Before
The search reference identifies a tread family. The brief still needs the full service description and vehicle or axle restrictions.
After
Record the manufacturer, revision, permitted rim range and any discrepancy for buyer review.
Evidence counter
This worksheet counts confirmed entries. It cannot determine compatibility or approve a substitute. Enter the values from the proposed SKU and compare them with your team's requirement. Use NHTSA TireWise for background on reading the vehicle placard and tire markings, then ask the manufacturer for exact-part specifications.
If your search starts with “Falken Wildpeak AT4W 285/70R17 approved rim width,” request the current technical sheet for the exact reference size and service designation. Ask each alternative supplier for its own approved rim range in inches. One listed tread and a matching nominal size cannot settle that range.
Illustrative review cases
A bidder lists the right rim diameter, but leaves the load and speed designation blank. Record the offer as incomplete and request the exact SKU sheet. If the verified description differs, route the deviation to the buyer's service lead.
A buyer asks for a larger casing to suit its route. Before accepting the proposal, compare the manufacturer's dimensional drawing and measurement rim. Ask the buyer's technical approver to confirm clearances on the loaded vehicle and to decide whether to authorize a sample.
A lower-priced bid omits lot traceability and its sample does not match the offered revision. Ask for the test method, the sample identification and the lot documentation the factory will supply. Keep any unresolved checks with the quote instead of treating the bids as equivalent.
Mark unresolved values as questions and tell us who can approve a proposed deviation.
