Size and load
Confirm the tire designation, load index and speed rating against vehicle requirements. Rim dimensions and approved inflation guidance also require product-specific review.
ENGINEERING STANDARDS
From stated requirements to documented evidence
Compare the intended application with product-specific specifications and the validation scope.
Explore the evidenceEvidence by application
Validation scope
Define samples, test methods and operating conditions before interpreting a result. A test on one size or duty cycle cannot automatically represent every product.
Market requirements
DOT/FMVSS requirements may be relevant to a product and destination market. Request the current evidence for the exact tire rather than treating a standard name as proof of approval.
Quality management system certifications and product regulations address different questions. IATF 16949 or ISO 9001 documentation, where applicable, must be checked for scope and validity; neither alone establishes approval of a tire. Batch identification and traceability requirements should also be agreed for the purchasing program.
For a reproducible comparison, record tire size, load index, speed rating, inflation pressure, axle load, route, ambient conditions and measurement method. Compare candidates on the same vehicle and duty cycle, then request the applicable product test report. A single trial cannot establish performance across all sizes, climates or vehicles; wet grip, rolling resistance and tread life may require separate tests.
Build a fitment review
Organize the inputs for a technical discussion. This checklist does not determine compatibility or replace manufacturer instructions.
Review checklist
Enter a vehicle and size to prepare a checklist for the technical discussion.
Request a scoped evidence review
Include the product family, size, destination market and intended use. Repeat the review when the duty cycle changes.
