California approves new rules for replacement tires
KCRA • • business
Key Points:
- California Energy Commission unanimously approved new regulations to phase out the sale of replacement tires that do not meet specified energy efficiency standards, aiming to reduce rolling resistance and improve fuel economy.
- The rules will be implemented in two phases: starting in 2029 with a maximum rolling resistance of 9.1 N/kN, and tightening to 7.2 N/kN by 2033, potentially saving consumers up to $153 in fuel costs within seven months.
- Tire manufacturers, including Goodyear, oppose the regulations, warning of significant cost increases and the elimination of about 70% of tires currently sold in California by 2033, while also raising concerns about enforcement and fairness.
- Environmental advocates support the rules for their potential to improve air quality and reduce emissions, and the regulations include exemptions for specific tire types such as motorsports, winter, and off-road tires.
- The new rules stem from a 2003 state law directing the commission to regulate tire efficiency, marking California as the first state to implement such standards, with ongoing industry collaboration planned during the rollout.
