Evaluation for SmartWay Verification of Low Rolling Resistance (LRR) Tires and Retread Technologies for Tractors or Trailers
Follow these steps for the evaluation part of the verification process:
Data analysis and interpretation.
Once documentation has been submitted, EPA will review the data, test reports, and any other related materials to determine whether the performance is suitable for verification.
Notice of Verification.
If all data and supporting documentation are acceptable, SmartWay will issue an official Verification Letter. This letter is legally binding and serves as the main indicator of a technology’s verified status.
Tire added to the Verified LRRs List
Once the tire is verified, EPA will add it to the Verified LRRs List.

Changes in a SmartWay Verified LRR.
Products sold as a verified LRR must be produced and installed as described to EPA.
Any changes to the tire:
- Must be documented and reported to EPA by emailing Tech_Center@epa.gov; and
- May require additional testing or separate verification.
EPA may revoke verification if the tire is changed without notifying EPA.
Audits of Verified Tires
EPA reserves the right to purchase and test verified tires and retreads in order to audit them.
If EPA determines that the tire's rolling resistance is higher than provided, then EPA:
- Will collaborate with the applicant to determine the reason for the discrepancy; and
- May revoke the tire model verification if it does not comply with performance requirements.
