California is Banning Your Tires – and Overregulating Your Life!
Breaking news: California is regulating more of your life. I know – it’s a huge shock! But apparently, regulating your gas-powered car wasn't enough…now our state is coming for your tires.
California has decided that the tires you currently buy aren't energy efficient enough, so starting in 2029, the state will begin imposing new efficiency standards on replacement tires. But don't worry – it's all for your benefit! The government says you'll save money, use less fuel, and reduce emissions. It's going to be wonderful!
But we've heard California make promises before. So today, we're going to look at what this regulation actually means for California drivers, what it's going to do to the tire market, whether the promised savings and environmental benefits are really worth the tradeoffs – and why this seemingly ridiculous story about tires actually tells us something pretty important about government, regulation, and freedom in California.
New Tire Regulations
Unfortunately, this regulation is nothing new, as our state has piled on regulation after regulation over decades to create the “big government” environment we all live in. This has, of course, reached into the automative industry, as Governor Gavin Newsom attempted to ban gas-powered cars in the future by phasing out their sales over years. That proved unsuccessful last year, as the United States Senate voted to block such a mandate,[1] stating the prioritization of radical environmental ideology over affordability and practicality for working families was not surprising, but unacceptable. But Gavin Newsom will not rest until he has something to show for the climate change activists he so desperately wants to appease, and that means your cars are still not safe – including the very tires you put on them.
Yes, you read that right – California is now regulating the very tires that you can put on your car, all in the name of … *wait for it* … CLIMATE CHANGE! So, what exactly is going on??
Earlier this month, the California Energy Commission passed fuel-efficiency standards for TIRES.[2] Back up – what does that mean? When you drive, your tires are in constant contact with the road. Revolutionary, I know. As the tire rolls, the part touching the road flattens slightly, and then rebounds back into shape. That constant flexing and rebounding requires energy, which means that for a gas-powered car, your engine has to burn more fuel to keep the car moving. That energy loss is called rolling resistance. The more rolling resistance a tire has, the more energy your vehicle needs to keep moving. The less rolling resistance it has, the less energy it takes, meaning better fuel efficiency for a gas-powered car and better energy efficiency for an electric vehicle.
Typically, the tires that come on a brand-new vehicle are designed to have relatively low rolling resistance because automakers have a strong incentive to maximize the vehicle's fuel efficiency. But when you eventually replace those tires, you have a much wider range of options – and some replacement tires have significantly higher rolling resistance. You as the consumer can prioritize things like durability, traction, performance, or price over maximum efficiency.
But California's new standards put a maximum limit on how much rolling resistance most replacement tires can have. The goal is essentially to make sure that when you replace the tires that came with your car, you can't replace them with tires that are significantly less energy efficient. The regulation will be phased in, beginning in 2029, with the full requirements taking effect in 2033.[3]
What is most important to understand here is that California isn't just encouraging you to buy more efficient tires. Our state is literally setting a legal limit on which replacement tires can be sold to you.
How are they justifying this regulation? The California Energy Commission says this move could save Californians nearly $1 billion a year in gasoline and electricity costs. It estimates that the first phase will add about $1.50 per tire to the cost, while the second phase beginning in 2033 would add about $6.50 per tire. But the state says those costs will be more than offset by the savings drivers get from improved efficiency. The state also says the program will reduce carbon dioxide emissions by roughly 2 million metric tons per year.[4]
So, basically, their argument is – yes, prices of tires will increase as the state requires certain types to be phased out and other manufactured, but in the long run you will save money and gas – win for you and win for the environment!
The Practical Effects
Naturally, we have to ask: What will this actually do? Because the California government makes a lot of promises. I would say it is one of their greatest skills! They are really good promisers! Yet, they rarely ever deliver on those promises. Have we solved homelessness? Do we have a bullet train across our state? No? Exactly. So, how realistic is it that this regulation will do any of the wonderful things our regulators promise it will do?
Let’s start with the supposed savings. The savings the CEC boasts sound good, but they are highly assumption-dependent – meaning they are not numbers we can say are guaranteed.
The CEC is modeling what will happen if:
replacement tires become more efficient,
those efficiency improvements translate into the modeled reduction in fuel consumption,
people drive the assumed number of miles,
the tires last the assumed amount of time,
the efficiency difference between today's replacement tires and compliant tires is what the CEC estimates,
and gasoline/electricity prices are around the assumptions used.
That is a lot of assumptions being made! Now, just to be clear, there's nothing inherently wrong with modeling – that IS how you estimate the effects of a regulation that hasn't happened yet. But we should be clear that the numbers they are citing is an estimate based on a set of assumptions, not money that has already been saved or is even guaranteed to be saved.
And we know this because the CEC's own estimates have changed substantially during the development of this program. In 2023, CEC staff estimated consumers could save $800 to $1,400 per set of four tires over the life of the tires.[5] Its much more recent analysis reduced the estimated savings for a typical gasoline passenger vehicle at about $179 per set.[6] Which just shows us that the numbers they put forth are projections, and projections can change when you change the assumptions and inputs creating them. We should be cautious then about treating a modeled $1 billion in future savings as though California has already put $1 billion back into the pockets of its residents – and we are right to ask questions to a state that has continually promised savings to taxpayers and then failed to deliver on those savings.
Now, while CEC’s projections are hypothetical, what is not just assumed is the effect this will have on the market for tires. Only 30% of tires in the market today meet the standards that will be in place by 2033.[7] Think about that! If you walked into a tire shop today and looked at 10 different tires that would fit your vehicle, roughly 7 of those 10 tires wouldn't meet California's future efficiency standard. So, while the state describes this as an efficiency standard, the practical effect is that it will eliminate a significant portion of the tires currently available to California consumers from the replacement market.
In short: California is changing the market. Manufacturers will have to make their replacement tires meet California's requirements if they want to sell those tires here. That means that, over time, 70% of the tires that are available to consumers today will either have to be redesigned or will no longer be eligible for sale in California. That matters because, as I mentioned previously, when you buy tires, you're usually not just choosing how much gasoline your car uses. You're choosing between things like price, tread life, wet-weather traction, handling, performance, durability, ride comfort, and specialized capabilities. The whole point of the free market is that different consumers can prioritize different things.
But what California is saying through this regulation is that rolling resistance and energy efficiency must be most important across the board for all consumers – and this has consequences. Tire manufacturers themselves say complying with this regulation will require more expensive materials and could affect affordability, competition, and consumer choice.[8]
According to the Tire Industry Association, average tire prices are likely to increase from $81 to up to $157.[9] That is a 93% increase! Dunlop Tires’ North America President and CEO echoed this concern, saying the cost of manufacturing will spike, and it then will be passed on to customers.[10] These estimates mean that if you go to replace all 4 of your tires, you’re looking at an average increase of over $300 as compared to what you pay now. Can you afford that?
Here’s the reality: every California-specific regulation creates another compliance requirement for companies doing business here. If manufacturers have to develop California-specific products, modify existing products, maintain separate inventories, or absorb additional testing/compliance costs, those costs will ultimately show up somewhere – in prices, product availability, or the decision to offer certain products in California.
But all of this – potentially higher costs and market shifts – could potentially be worth it, if the desired goal is achievable and important. Which leads us to ask: is this going to actually help the environment in the ways promised?
The CEC estimates the regulation will reduce greenhouse gas emissions by about 2 million metric tons of CO₂ equivalent in 2035.[11] And the basic theory makes sense – if tires require less energy to move the vehicle, then gas-powered vehicles should use less gasoline, and electric vehicles should use less electricity. But, how significant is that environmental benefit compared with the enormous scale of California's transportation emissions?
Two million metric tons of reductions would equal about 1.9% of California's passenger-vehicle emissions using 2021 numbers.[12] Under 2%! We’re talking about an entirely new market for tires, and potential increased costs to consumers in the short-run, for a relatively small – a completely unnoticeable – decrease in the percentage of the emissions from passenger vehicles. This is where we MUST evaluate cost versus benefit. How much government intervention, and how much restriction on consumer choice are we willing to accept for tiny, incremental improvements? How much will this make a difference to the overall environment and climate?
This reveals to us what we already know from previous regulations just like this: California's approach to environmental policy is absurd. You can make almost any regulation sound impressive if you only talk about the number in isolation! Saying, "We're going to eliminate two million metric tons of emissions!" sounds like a lot. But if that represents less than 2% of the emissions from the very sector we're targeting, suddenly you come to realize it’s a whole lot of cost for virtually no benefit.
And we cannot forget, that similar to cost savings, the 1.9% figure isn't a measurement of what California has already accomplished, but is the CEC's projection for 2035, based on its assumptions. So we could not even hit that meager goal!
If the goal is to make a meaningful difference in California's emissions, shouldn't we be looking for policies that actually make noticeable change? Instead, we're regulating the tires on your car so that we can capture a projected 1.9% reduction in passenger-vehicle emissions. The benefit is not by any means large enough to justify the government intervention required to achieve it. This is once again virtue signaling – California is simply adding another regulation because regulating something makes us feel like we're doing something.
Now, as we are talking about costs, there is one more consideration that is even more important than monetary costs here – and that is safety. Tires are literally the thing that keeps your car connected to the road, meaning they matter a whole lot!
Fuel efficiency isn't the only thing a tire is supposed to do. Tire manufacturers have to balance rolling resistance with other characteristics, including traction, braking, handling, tread life, durability, and performance in different driving conditions.
Maybe as the consumer, you want the tire that gets the best fuel economy. But maybe you don’t! Maybe, instead, you want one that lasts longer. Or maybe you live somewhere where you need excellent wet-weather traction – ahem, Los Angeles when it rains. Maybe you prioritize handling and performance. And if you're suddenly forced into an evasive maneuver on the freeway – especially in California where we have legitimately CRAZY drivers – you're probably not thinking about how many gallons of gasoline your tires saved you that month! You're thinking about whether those tires are going to grip the road.
Opponents to this regulation have voiced these exact concerns, calling out the fact that tires with less rolling resistance are safest in a straight line, but do not perform as well handling corners or turns.[13] So, the unknown question on the minds of consumers in California becomes whether tire manufacturers are going to be able to optimize the new rolling resistance requirements at the same time as considering grip, tread life, and price.[14] I’m not entirely thrilled to find out the answer to that question through real-life experience.
The Bigger Problem: California’s Regulatory Environment
Now, after everything we've just talked about, you might be thinking, Tess, it's tires. Is this really that big of a deal? But that would be to completely miss the bigger problem here! The problem isn't necessarily that California decided to regulate tires, the problem is the greater regulatory environment in our state and the mindset behind it.
This is one more example of California looking at an area of ordinary life, identifying a problem that it believes it can improve to align better with its ideology, and then deciding that the solution is going to be another government mandate. One regulation may not seem like a big deal in isolation, but we who all live in this state can agree, it’s hardly just one regulation! When you look around here, you realize that our government is involved in almost every aspect of your life.
Which means this is the perfect opportunity to bring the conversation back to the principles of limited government.
We need government. We need laws, standards, and even regulations in certain circumstances. Government has a legitimate role in protecting its people, protecting property, maintaining public safety, and addressing problems that genuinely cannot be solved effectively by individuals acting on their own. But the beauty of limited government is that it recognizes that government cannot be limitless.
Not every problem is a government problem! Not every solution to a problem should become a government mandate. And not every ideology valued by our government justifies taking rights or freedoms away from individuals. But in California, our lawmakers believe that every area of life that does not conform to their ideological views is a problem for the government to solve with more rules – and in this case we see that individual liberty and consumer choice are sacrificed on the altar of environmental regulation.
We have allowed California to establish the principle that government should intervene whenever it can identify a measurable benefit, but if that is the case then very quickly, we are hit with the reality that there is almost no limit to what government can justify regulating. We just assume that if something isn't working, we need more government.
But with every regulation, we should ask: Does this actually solve the stated problem? Is the benefit significant? What does it cost? What are the unintended consequences? Are there better alternatives? And most importantly, is this something government should be doing in the first place?
This relates directly to this election season we find ourselves in! California passes hundreds – close to a thousand – new laws every year, and in one election cycle we are voting on FOURTEEN propositions. If they all passed, that alone is 14 new laws in place, regulating and changing our lives. This means that we should take every proposition put in front of us incredibly seriously, with the weight of our freedoms on our shoulders.
Here's what California doesn’t want you to know: free people are capable of making a lot of decisions for themselves. We need to choose freedom over ideology. Seemingly good goals do not automatically justify unlimited government power. Government exists to protect our freedom – not to manage every aspect of our lives.
So, will California's new tire regulations save us money and help the environment? Likely not. But that's not even the question we should be asking! We should be asking whether government should be making this decision for us, and whether we really want to continue down a path where we regulate ourselves out of existence.
Because at some point, we must recognize that freedom means more than getting the outcome the government thinks is best for us. It means having the ability to make our own choices, accept the consequences of those choices, and live as free people rather than subjects of an ever-expanding government.
