It cost me $1600 to change the 4 tires for my Tesla because they are “energy efficient” and matched my original tires. I do not want the tires for my other car to be this expensive. I don’t care about efficiency those tires are literally 4X the price of my other car a Honda.

My Honda’s energy efficient tires are cheap. Your Tesla tires are expensive because of their lower volume and high performance design. They have different compound and more durable construction to handle the weight and torque better, and have noise dampening inserts.

An energy efficient tire for a Honda is just a mid priced tire for a Honda, and probably cheaper to install because they likely use just a $0.50 rubber valve stem too.

Isnt that because it has crazy torque, AWD, and high weight?

Same thing with ebike tires vs normal bike tires

Mine are really close to needing to be replaced and I’m not looking forward to the 1500+ it’ll cost. I’ve gone further than the est lifespan at least.

Are the wheels a weird size? What stopped you from replacing them with regular tires?

Not the OP, but for my EV, it was a combination of higher load rating because batteries are heavy, tread compound needing to be different (more expensive) because of high torque requirements, and rolling resistance and tire noise being much more important for EVs than ICE cars.

most of a passenger car's performance and handling is its tires

  ...“designed to ensure that replacement tires sold in the state are at least as energy efficient, on average, as tires sold in the state as original equipment.” 
My nose for unintended consequences says manufacturers could start selling cars with worse tires to bring down the average.

That being said, the quoted figures do sound good. Maybe less compelling in someplace like Texas with very low gas prices:

  The energy commission calculated that more efficient tires cost between $6 and $26 more per set, but that increase is more than offset by reduced fuel consumption. It put net savings at $85 to $153 over the lifetime of the tire when gasoline is $4.60 a gallon, though the savings could be 25 percent higher with this year’s price spikes.

> manufacturers could start selling cars with worse tires to bring down the average.

OEMs do the opposite already because their official MPG ratings are calculated using the OE tires. OE tires are sometimes criticized as prioritizing fuel economy too much at the expense of longevity and performance.

I don’t see a reason that a car manufacturer would be incentivized to help tire manufacturers sell the cheapest tires on the market

They won't want to do that because it'll hurt their advertised mileage/range.

This is aimed at the different incentives between selling tires to manufacturers (make sure mileage is good, balance that against raw cost) vs direct to consumers (up front cost is king).

There are doubtless still some potential loopholes that will be explored, though some of the most obvious (like reducing tread depth, mentioned here, appear to have been considered already: https://www.roadandtrack.com/news/a71509031/california-tire-... ). It doesn't appear to be that naive.

It's also something that's hard to find info on when shopping for tires, so more transparency should help consumers.

I’d be much more interested in particulate pollution limits for tires.

Looking forward to picking up new pilot sports in Nevada.

Same. It seems like they will just give them one leaf marking and not outlaw them outright, though?

TIL we have LED lightbulb rules but every bulb in home depot has terrible PWM that's bad for your eyes.

Another 20 years and maybe the government will finally address that.

On the tires topic, I'm fine with this as long as they don't ban the sale of anything. Let the consumer decide.

Dual feeling about this.

Non-OEM tires are usually louder, because they trade in efficiency for noise.

OTOH I had a car that came with Michelin Super Ports and it was a much better ride on Michelin PS4S.

Typically, there's a trade-off between rolling resistance/energy efficiency and traction/low noise. It's very easy to make long-lasting, efficient tires that are unsafe. It's difficult to make them both categories and quiet.

Maybe single occupancy personal vehicles are wasteful and mass transportation should be invested in rather than shaming individual into token behaviors compared to large-scale waste and consumption sources elsewhere in the economy?

I would like to see a rule added that requires embedding a uuid for each tire so if you litter it, or your trucking company loses a re-tread, the state can chase you down and bill you, even years later. Upon selling a vehicle or replacing tires, your name is taken off the liability list and transferred to the new owner or shop. The retreads alone cost the state quite a bit and are dangerous to remove from the traffic lanes.

Do TPMSs have uuids? Although I suppose it would just be a matter of time until Flock tracks those too, if they don't already

What a silly law. If a tire is "inefficient" and therefore "bad", why can't California just ban the sale of them? Instead there will be a new government funded office and rating system with "leaf" icons that 95% of consumers will ignore completely.

Like all types of laws like this, the "$1B" claim will never be reviewed or judged to see how accurate it is. (It's not, at all)

Because things aren't as simple as you make up.

"why can't California just ban the sale of them" -- because that infringes freedom too much? There are probably lots of special machines with tires (e.g. in construction, farming, mining) that absolutely need "bad tyres". Because only they work, e.g. due to construction form or physical properties like maximum pressure.

If some armchair person now goes here and outright bans all tyres that don't match some efficiency numbers ... then all of the users of such equipment will be punished. THAT would be an overreaching government action.

However, having some labels that indicate to those customers that care (and can care, because they don't have to consider other constraints) is actually something that enlarges freedom. You get the info, you can act on it, but you're still free to NOT act on it should the circumstances for that be okay. And ultimately it's you that decides this, not some government authority.

It'll never get reviewed. They'll distract them with something other piece of news.

And don't be shocked if a bunch of California government officials bought a bunch of Goodyear stock right before this.

Isn’t it doing both?

SpicyLemonZestabout 2 hours ago
I understand how the article could make it sound like they're doing some kind of complicated matching process, but what California is doing here is pretty close to just banning the sale of them. They're establishing the rolling resistance coefficient as the state's official measure of tire efficiency, attaching a leaf ranking to different ranges, and through 2031 phasing in maximum values which tires must meet to be sold.
