Size and rim
Compare the full size designation and approved rim range. If the supplier gives only nominal diameter, keep the offer open until the required dimensions and fitment are supplied.

SPECIFICATION DASHBOARD
Four lines to verify before award
Example of a specification line, not a fitment recommendation: 225/65R17 102H records a 225 mm nominal section width, 65 aspect ratio, radial construction and a 17 in nominal rim diameter; 102 and H record load index and speed rating. A supplier’s comparable response should repeat the full designation and identify any deviation. Keep the original vehicle approval and proposed product sheet together so another reviewer can reproduce the comparison.
Load and speed
Record the required service description beside the offered designation. For applicable commercial setups, ask for the manufacturer’s load and inflation data for the actual single or dual installation.
Tread and duty
A fleet buyer may favor uniform tread across locations to simplify stocking. A maintenance lead may prefer application-specific patterns for wet or mixed surfaces. Ask both teams to specify the operating conditions that would justify a separate request.
Production and release
A small sample can surface a specification gap early, while an immediate full-order quote may improve the commercial comparison. Ask how sample production relates to the proposed order and what must be confirmed before release.

ACCEPTANCE SEQUENCE
Keep records through the decision
Before requesting prices
Mark the vehicle-approved fitment and log who can accept a deviation.
Before comparing proposals
Read the supplier’s evidence against the quoted model and size. Do not transfer a test report or marking from another proposal.
Before placing an order
Ask the supplier to confirm the final drawing or technical sheet, quantity, origin, destination, and quote exclusions in writing.
PROCUREMENT DESK
Review the open specification items
Send the requirements you have and identify which dimensions, load details or documents still need confirmation.
