California tire efficiency regulation

Entities: California · California Energy Commission · Harrison Reilly

Overview

In early July 2026 California announced a proposal to tighten standards for replacement tires, aiming to boost vehicle fuel efficiency and cut emissions. By late July, the California Energy Commission released a revised draft after a public comment period. The update introduced exemptions for a wider array of tires—including all‑season snowflake‑rated tires, certain competition, run‑flat, off‑road, and ultra‑long‑life models—while also postponing implementation dates. Phase 1 now applies to tires built from January 1 2029 (instead of 2028), and Phase 2 is shifted to January 1 2033. The commission will consider adopting the rules after the comment deadline on August 3.
