Verified Technologies for SmartWay and Clean Diesel

Overview of the SmartWay Verification Process for Low Rolling Resistance (LRR) Tires and Retread Technologies for Tractors or Trailers


Due to the complexity of the verification process, EPA cannot guarantee specific time frames for completion. However, manufacturers can expedite the process by providing immediate, accurate, and complete responses to all EPA inquiries.

The SmartWay Verification Program evaluates the ability of LRRs to reduce resistance and improve fuel economy or emissions for Class 8 tractor-trailers.

Please complete this process for each tire model that you would like verified.

There are four parts to this process:

Part 1: Requirements

Make sure you meet the device eligibility requirements before applying.

Part 2: Contact Info

Provide contact information in a web form.

Part 3: Application & Testing

After submitting contact information, email additional materials to EPA. These materials include an application, testing materials, and other marketing materials.

Part 4: Evaluation

Evaluation includes data analysis and interpretation, receipt of a Verification letter, and if accepted, inclusion on the Verified Devices List.
