CA Tire Replacement Controversy: The 2026 Regulations are Regulatory CHOICES by Energy Commission

The California Energy Commission’s newly adopted replacement-tire regulations have been reduced to a simplistic storyline: “Legislators passed a ‘bad bill’ tire-efficiency law.” That framing leaves Californians with an incomplete picture and misses some critical issues pertinent to non-elected commissions implementing the “will of the Legislature” decades after every member of that voting body has either died or left office, including the Governor who signed it.

KCRA Sacramento and other news outlets correctly identified the origins of the program in a 2003 statute. But their reporting failed to clarify or question the distinction between what the Legislature actually enacted in 2003 and the specific regulatory restrictions the California Energy Commission adopted in 2026. That distinction matters and raises concerns over who even oversees enactment of state laws and increasingly expansive powers utilized by non-elected commissions.

The 2003 Legislature did not prescribe the precise tire restrictions adopted twenty-three years later by today’s Energy Commission

The 2003 legislation was Assembly Bill 844, authored by then-Assemblyman Joe Nation. It directed the California Energy Commission to develop a statewide Replacement Tire Efficiency Program for passenger cars and light-duty trucks. The statute established a policy objective: replacement tires sold in California should be “at least as energy efficient, on average,” as tires installed as original equipment on new vehicles. 

One can argue whether the Legislature should even have established a policy objective on the issue, but words matter under the law. The 2003 Legislature did not prescribe the precise tire restrictions adopted twenty-three years later by today’s Energy Commission. The law contemplated a database of tire-efficiency information, an efficiency rating system, manufacturer reporting, consumer information, and minimum efficiency standards. 

That is far different from implying that legislators enacted the exact numerical rolling-resistance limits, implementation dates, exemptions, and market consequences contained in the regulations adopted twenty-three years later. The 2026 regulations are regulatory choices developed through the Energy Commission’s rulemaking process decades after the original legislative vote. That should be newsworthy and reported to the public because more fundamental questions have not been asked, including: How closely do the regulations adopted in 2026 reflect the 2003 intent, and does the time gap between passage of the bill and adoption of the regulations highlight concerns that, because of term limits, Sacramento’s bureaucracy can “wait out” voting legislators and write regulations decades after elected officials leave Sacramento? 

These are questions news outlets should be asking. But they are not. This is especially important because the practical consequences are now being debated.

Some tire company representatives have warned that the 2026 rules could eliminate a large percentage of replacement tires currently manufactured from eligibility for sale in California and could increase costs. The Energy Commission disputes the more alarming cost projections and argues that compliant tires will ultimately save motorists money through reduced fuel consumption, emphasizing that approximately 70 percent of tires already comply with their initial standard. Those competing claims deserve scrutiny. 

AB 844 was not a blank check

The Legislature imposed conditions on the development of efficiency standards. The statutory framework required consideration of technical feasibility and cost-effectiveness and protections against adverse effects on tire safety, average tire life, and California’s scrap-tire management efforts. Those safeguards were considered important because tires connect a vehicle carrying human life to the road. 

The Energy Commission says its analysis demonstrates that the standards are technically feasible and cost-effective and will not compromise safety or shorten tire life. It projects that the program could eventually save California drivers nearly $1 billion annually in fuel costs and reduce greenhouse-gas emissions by approximately 2 million metric tons per year. Those are the Commission’s findings. They should be examined against the industry’s evidence and the actual language of the statute. 

What caused this extraordinary twenty-three-year delay?

But there is another historical fact that is particularly newsworthy: what caused this extraordinary twenty-three-year delay, and should there not be better tracking oversight of enacted legislation and timelines for the promulgation and implementation of enacted statutes? Who should do this in California? Indeed, my first response when learning of the regulations was that this seemed outrageous—not only due to the extraordinary time delay from legislative action to adoption but also because legislation does not always prescribe specific metrics. So, what exactly had been passed and what had been implemented? 

Undoubtedly, the 2003 Legislature did not envision waiting for two decades for the law to take effect. California’s Legislative Analyst’s Office noted that AB 844 required the Energy Commission to adopt and implement the program within a narrow timeframe. This raises legitimate questions of democratic accountability. The legislators who voted on AB 844 were voting in 2003, based on the technology, tire market, vehicle fleet, gasoline prices, and policy assumptions of that era. The 2026 regulations adopted were written through an administrative process in a politically different era two decades later. 

That does not automatically make the proposed regulation unlawful or even good vs. bad policy. Administrative agencies routinely implement statutes through regulations. But a more accurate news headline should not simply be “California Legislature passed a bad tire mandate that we now have to live with.” Given the timespan delay from bill passage to enactment of regulations, it would be beneficial for news outlets to examine the language of AB 844 alongside the final 2026 regulations so we might understand where the two align and where in the framework the Commission may have made consequential regulatory choices of its own. The Commission should explain why the standards adopted in 2026 are consistent with the Legislature’s intent, as well as why it took 23 years to implement them.

Ultimately, this isn’t merely an argument about tires or safety or affordability. There is something bigger at stake that few seem to be discussing: Who actually makes California law—the legislative body or unelected regulatory agencies? How much authority should legislators delegate—intentionally or not—to unelected regulatory agencies who have the power to “wait out” legislators and governors in an era of term limits in rendering their interpretations of legislative intent? And does California even have a viable and enforceable government oversight power to track a bill’s afterlife once it has been signed into statute? 

With hundreds of bills still waiting to be voted upon in the final days of the session, it might be a good time for both legislators and the governor to pause the paper shuffling and seek answers to what should happen to bills like AB 844, which was orphaned for twenty-three years.
