California First US State to Mandate Energy-Efficient Replacement Tires

California has enacted groundbreaking regulations, becoming the first U.S. state to mandate energy efficiency for replacement tires. This significant auto industry rule aims to phase out older, less efficient tires and promote greener vehicles on the road. State regulators assert the new rules will cut emissions and reduce fuel expenses for drivers.

However, the policies, approved unanimously by the California Energy Commission (CEC), have already ignited opposition from conservative circles. One conservative news outlet decried the regulations as a "massive overreach." The Trump administration has also been actively challenging California's authority to implement stricter environmental regulations for vehicles.

Environmental and clean-air advocates have lauded the CEC's decision, expressing hope that other states will follow California's lead. The first phase of the regulations is scheduled to take effect in 2029. The standards require that replacement tires achieve, on average, the same energy efficiency as tires sold with new vehicles. The CEC notes that drivers often lose mileage or electric vehicle range when using older replacement tires, which typically have higher "rolling resistance" compared to the low-resistance tires found on new cars.

California drivers want to save money and want to reduce harmful emissions, so I think Californians will be very pleased by having higher-quality tires on the market.

The CEC estimates these standards will save California drivers nearly $1 billion each year in gasoline and electricity costs. Furthermore, the regulations are projected to reduce carbon dioxide emissions by 2 million metric tons annually, an impact equivalent to removing approximately 400,000 gasoline-powered cars from the road. Bill Magavern, policy director for the Coalition for Clean Air, highlighted the regulations' dual benefit: "California drivers want to save money and want to reduce harmful emissions, so I think Californians will be very pleased by having higher-quality tires on the market."

While major tire manufacturer Michelin has voiced support, aligning the policies with its commitment to reducing the environmental impact of tires, other industry groups and manufacturers have raised objections. In an April letter, Goodyear, Yokohama, and the California Tire Dealers Association expressed concerns about increased costs for replacement tires, estimating a rise of $6 to $10 per tire. Despite these industry concerns, proponents emphasize the environmental benefits and potential cost savings for consumers.

This will make tires more efficient, reduce emissions that cause air pollution and climate chaos … and save money for drivers who these days are faced with high fuel costs.
