California’s new tire efficiency rules could save drivers $1B a year
The nation’s first tire efficiency standards target an overlooked drag on fuel economy that can cost drivers more at the pump.
California has become the first state to introduce a rule addressing inefficient tires, which could save drivers up to $1 billion annually. This new regulation, approved by the California Energy Commission, aims to ensure that replacement tires sold in the state are as energy efficient as those originally equipped on vehicles. The rule also involves a labeling system that assigns a "leaf" rating to tires, making it easier for consumers to identify the most efficient options.
The changes are projected to reduce carbon dioxide emissions by 2 million tons annually, equivalent to taking around 400,000 cars off the road. Phased into effect over two stages, the rule initially targets the least efficient tires starting in 2029 and a more stringent standard in 2033. Some manufacturers support the initiative, while others express concerns about the cost, with estimates suggesting the tires could be $6 to $26 more expensive per set, but still yielding significant savings.
The rule also excludes snow tires, competition tires, and all-weather tires, which are tracked separately. Despite criticism from some stakeholders, supporters believe this regulation marks a significant step forward, potentially influencing other states to follow suit.
