California's Proposed Replacement Tire Efficiency Program
Monday, 17 August 2026, the California Energy Commission (CEC) approved the Replacement Tire Efficiency Program (RTEP), the nation's first efficiency standards for replacement tires sold for passenger vehicles and light-duty trucks in California. Item 9: Final Environmental Report and Replacement Tire Efficiency Program Regulations (Docket Nos. 24-TIRE-01 and 26-TIRE-01) 17 August 2026 Business Meeting - CEC Approves Nation’s First Replacement Tire Efficiency Standards, Saving Californians Billions in Fuel Costs - Replacement Tire Efficiency Program Proceeding - Tire Efficiency Rulemaking Docket Log - The enforcement dates for California's Replacement Tire Efficiency Program regulations are structured in a two-phase rollout: Phase 1 Enforcement: 2029 (applies to covered replacement tires manufactured on or after 1 January 2029). Phase 2 Enforcement: 2033 (introduces stricter efficiency and rolling resistance limits). (Note: These dates reflect a one-year delay for Phase 1 and a two-year delay for Phase 2 adopted during the 17 July 2026 amendments prior to the final approval on 17 August 2026).
The California Energy Commission (CEC) proposes to adopt the Replacement Tire Efficiency Program Rulemaking in the California Code of Regulations (CCR), Title 20, Chapter 14, Article 1, Sections 3301 through 3310 to implement the Replacement Tire Efficiency Program pursuant to Public Resources Code Sections 25770, 25771, 25772 and 25773. The CEC proposes new regulations to increase the energy efficiency of replacement tires for passenger cars and light–duty trucks. The proposed regulations set minimum performance standards for the energy efficiency and wet grip performance of replacement tires sold in California. The regulations will also set reporting requirements for tire manufacturers and brand name owners, and only tires listed in a CEC database will be legal for sale in California. The proposed express terms include the CEC staff’s consideration of comments, objections, and recommendations regarding the proposed regulations received during prerulemaking stakeholder engagement. The CEC will hold a public hearing for the proposed regulations on 10 June 2026 from 10:00 AM - 05:00 PM (Pacific Time) Remote Access Only Webinar ID 893 2150 5373, passcode 198841.

The resolution would also delegate authority and direct staff, on behalf of the CEC, to take all actions reasonably necessary to have the proposed regulations go into effect. The CEC issued notice of the proposed rulemaking, including the express regulatory terms, which was published in the California Regulatory Notice Register on April 24, 2026.
