Yes, there are trade-offs, but you can get really great tires on all three. The Michelin CrossClimate2 tires are arguably the best traction tires, Consumer Reports estimates 95,000 miles of tread life in their testing (higher than basically anything else), and they got a 4/5 for rolling resistance on Consumer Reports' dynamometer testing.
There's a lot of tires that are poorly made and just bad tires. For example, one tire got 2/5 for rolling resistance, tested to 55,000 miles for tread, and 2/5 and 3/5 ratings for the traction categories like wet braking, snow traction, ice braking.
I'm not arguing that there aren't trade-offs, but tire companies have been working to make better tires that minimize the trade-offs and produce better tires on all three.

It sounds like the rule isn't exactly that strict. This (combined with the fact that all season tires aren't covered) presents a very low bar. But there are tires that are just garbage - they're bad at all three. It doesn't sound like this rule would impact good tires that have very long tread life and amazing traction. It sounds like it'd impact the tires that are a pile of garbage.
There's a difference between a tire that trades off a small portion of rolling resistance for traction and tire wear and tires that are poorly made and are trading off a huge amount of one or two of those categories because they're just bad tires.
It's worth pointing out the CrossClimate2 tires are all-seasons and exempt from the requirement. The 4/5 is specific to Consumer Reports all-season category - actual efficiency is going to be noticeably lower than the high efficiency tires they are talking about in the article.
But you're not wrong in general. There are a lot of garbage tires. And that's not even considering the intentionally "bad" tires like the knobby off-road treads that also have the side effect of massively increasing road noise and reducing engine life.
But like a lot of the California rules, they have carved out so many exceptions and have no real enforcement mechanism (the worst offending tires are being imported directly from China). So the reality is that there is not going to be a lot of juice for the squeeze.
The US military-industrial complex is the single largest institutional hydrocarbon consumer and greenhouse gas emitter on the planet. It would be pretty stupid for me to listen to the government's advice about how best we should preserve the environment.
So the issue is under regulation, yeah, agree on that point.
Sounds like the only reasonable solution to the problem you raise is that the part of our government that's responsible for defense should be put under the seperate part that is responsible for protecting our environment instead of being exempt. I can't see any other real way of resolving that issue can you?
Because government self regulation totally works and the resources used up and the size of the government has not grown by such magnitudes that would make the founding fathers rethink the whole idea of democracy?
Ok, so no particular disagreement or pragmatic pitched alternative, great! I agree, structurally improved government and regulations is the only definable way forward for me too.
China has been the largest ghg emitter for the last 20 years, and currently emits more than twice as much as the us. Gdp spent on defense is similar as a fraction of gdp (slightly more in the us). So realistically the Chinese military is by far a larger emitter of ghg than the us military.
> The Michelin CrossClimate2 tires are arguably the best traction tires,
In their class, but not in general.
They are all-season tires. They don't perform as well as winter tires in the winter, and they don't perform as well as summer tires in the summer.
They're also a terribly mushy tire. They feel like you're floating around on the road and wallowing through the turns. This doesn't matter in the slightest to someone commuting to work in their 15 year old Honda Accord with blown struts, but if you enjoy driving they're on the list of tires to avoid.
Everything is a tradeoff. Some tires do a better job of optimizing within their class, but the Michelin CC2 is assuredly not the best traction tires in general.
>They don't perform as well as winter tires in the winter, and
A lot of people don't live in climates where winter tires are even sold; particularly California, Texas, Florida, three of the most populous states. Many people in those states aren't even aware "winter tires" are even a product category. That's like complaining the Walmart in Anchorage, Alaska doesn't carry SPF 50 sunscreen.
Just as a geographic note: You can buy winter tires in California. The Sierra Nevada (snowy mountains) run down a sizable chunk of the state. California has even hosted the winter olympics.
You left the "and" but left out the critical part of my quote: They're not as good as summer-only tires in the summer.
> A lot of people don't live in climates where winter tires are even sold
The CrossClimate 2 tire we're talking about is an all-weather tire with the 3-peak snow designator. If you're trying to call me out for talking about winter tires in comparison to a tire designed for winter weather, I think you don't understand what we're talking about.
> Many people in those states aren't even aware "winter tires" are even a product category
Again, the CrossClimate 2 is a tire with a winter designation. California also has a lot of snowy locations.
> That's like complaining the Walmart in Anchorage, Alaska doesn't carry SPF 50 sunscreen.
Not only do stores in Anchorage carry SPF 50, but you're going to need it in the summer. When the sun is out for 20 hours a day, it adds up.
My Mach-E came with CrossClimate2 tires and I am not impressed. I've accidentally lit up all 4 tires under hard acceleration on a dry road, despite 5000 lbs pushing them into the ground and some amount of traction control still active.
I have a lighter sports car making similar power, on Michelin Pilot 4S summer tires. That car just grips and goes with barely a squeal. Good summer tires also have far better wet performance than CC2s, and they provide better feedback.. you feel more planted and in control.
I am impressed overall with the CC2's ability to be a true all-rounder that is usable in snow, but it is still an exercise in trade-offs and it'll never be as good as any purpose-built tire is at its purpose.

That is incredible. My front ones are toast after only 15 000 miles / 25 000 km ( Continental Sport Contact 3 / N0 rating) and two years. 95 000 miles and I'd need to change them not because of wear but because they'd be legally too old.
Indeed, I put a full set of CrossClimate2 on my German car and the two back tires were completely toast within 24 months and ~15k Km (on Canada). After that I decided to start using proper summer and winter tires.
Have any of yall given up on “nice tires” due to constant nail / screw punctures and subsequent loss within a very low mileage count?
I believe I spent $1200 on my last set only to lose two of them in the first six months due to road debris. Perhaps this is down stream of living in a boom state with constant construction but I’m nearly replacing cracked windshields and at least partial tires annually as of late.
There's a lot of tires that are poorly made and just bad tires. For example, one tire got 2/5 for rolling resistance, tested to 55,000 miles for tread, and 2/5 and 3/5 ratings for the traction categories like wet braking, snow traction, ice braking.
