State Looks To Regulate Tires

California drivers already face an extensive list of regulations governing their vehicles, and now the state is adding another item: replacement tires.

The California Energy Commission unanimously approved new efficiency standards that will eventually prevent certain replacement tires from being sold in the state if they fail to meet requirements involving rolling resistance.

State officials say the rules are designed to save motorists money by reducing the amount of energy vehicles need to move down the road. Critics, including representatives of the tire industry, warn that the regulations could instead raise the upfront cost of buying tires and reduce consumer choices.

“This ultimately is about protecting consumers,” California Energy Commission Chairman David Hochschild said, according to KCRA. “I see this as sheltering the public from higher costs in the long run.”

Commissioner Nancy Skinner made a similar argument.

“These regulations are a tool within our authority that can save money for every Californian,” Skinner said.

The disagreement centers on something most drivers probably do not think about when buying tires: rolling resistance.


Rolling resistance measures the energy required to keep a tire moving. Tires with lower rolling resistance can improve fuel economy in gasoline-powered vehicles and increase efficiency in electric vehicles. California regulators are betting that those energy savings will ultimately outweigh any consequences created by restricting which tires can be sold.

Manufacturers are not universally convinced.

Bret Gladfelty, speaking on behalf of Goodyear, told commissioners that the requirements would increase costs for consumers and argued that unresolved technical and legal issues remained.

The scale of the potential market change is substantial. KCRA reported that roughly 70 percent of replacement tires currently sold in California would not comply with the new standard. That does not mean 70 percent of tires will immediately disappear, however, because manufacturers can redesign products and bring additional models into compliance as the requirements take effect.

Still, the regulation puts California in unfamiliar territory. The California Energy Commission has never regulated tires before, and California is the first state to adopt such a rule.

That distinction has already prompted some critics to wonder whether Californians will simply cross state lines to purchase tires that are no longer available at home.

RedState Managing Editor Jennifer Van Laar joked about what could happen in Primm, Nevada, located immediately across the border from California.

“Just wait until Terribles opens a 50-bay tire center at Primm,” she wrote.

It is a sarcastic observation, but it points to a practical issue whenever one state imposes product restrictions unavailable in neighboring jurisdictions: consumers can sometimes take their money elsewhere.

The tire standards also arrive against the backdrop of California’s broader attempt to reduce transportation emissions. Gov. Gavin Newsom announced in 2020 an effort to end sales of new gasoline-powered passenger vehicles in California by 2035, although federal policy and litigation have complicated the state’s ability to carry out that mandate.

Skinner, meanwhile, indicated that she believes tire regulation has been overdue.


KCRA asked her whether she had personally driven the latest rulemaking effort. She described it as a joint effort by the commission rather than directly claiming responsibility.

“If I had been on the commission 20 years ago, maybe it wouldn’t have taken so long,” Skinner said.

Asked why the commission had not acted sooner despite legislation dating back roughly two decades, Skinner suggested economics had changed.

“There may not have been those cost pressures,” she said.

For regulators, the calculation is straightforward: more efficient tires mean vehicles require less energy, which they contend translates into lower operating expenses for drivers over time.

For opponents, the calculation starts somewhere else entirely — at the tire shop.

If compliant tires cost more, consumers will encounter that expense immediately, while any projected savings accumulate gradually through fuel or electricity consumption. The argument therefore is not simply over whether lower rolling resistance improves vehicle efficiency. It is over whether California regulators should decide that the efficiency benefit justifies removing noncompliant products from the state’s marketplace.
