Hate gun roster, hmm how about tire roster?

Exactly!!

This parallels the gun control debate. It's rarely possible to regulate human behavior, and it's human behavior that is the very core element in all of this.

So what is really being accomplished? Posturing. Posing. "Look what we have done!" intone the regulators and politicians. "... For the Children! No less!"
children and safety are always used as tools for these kinds of things. it is quite tiresome, really
 
I'm not defending these regulations because I haven't seen the data, but in theory if 20 million cars got 1mpg better mileage even though they had the same habits as far as keeping their tires filled, there would still be a significant cost savings. And that's not just consumer cost, there are secondary costs that go along with these things like smog and carbon etc. Long ago people were reactionary about smog regulations but they literally worked, same with the ozone layer it literally worked and recovered, same with low flow toilets and bath fixtures it saved a lot of water.
name one thing that was regulated and actually had 'cost saving' with it. the EPA's regulations alone are costing californian's roughtly an extra 2k a month of cost of living than another state
 
but they literally worked, same with the ozone layer it literally worked and recovered, same with low flow toilets and bath fixtures it saved a lot of water.
comical. yeah, all that from california's regulations. do you seriously believe that? go look at another state without all this, and you will see the exact reality of california
 
It is interesting that people are ignoring what CA is ignoring.

A steel wheel has lower rolling resistance, but guess how it does in terms of traction.

From what I have seen the tires will last half as long, meaning that you will have to replace it twice as often. So where is the energy savings with that?

There is NO mention of the safety of the tire, such as traction and other aspects. Who cares about braking distance, right? Who cares if you can't control it when there is snow and ice. That means more people are likely to be killed or injured, but that won't count against it, just like those who die because the government has prevented them from defending themselves doesn't count in the gun control debate.

I drove a rental vehicle in snow and ice, with the tires that they claim they want, same or better than factory. I got stuck three times in a parking lot with snow and ice, twice within minutes of each other. To a sane person having tires that work better as to what they are supposed to do is far more important that a very slight difference in fuel economy.

Respectfully, you're missing the point. People check tire pressures maybe when a warning light illuminates on their dashboard. And yet tire pressure is an important variable in all of this.

A useful reference: Low tire pressure significantly impacts fuel efficiency. According to the US Department of Energy, for every 1 PSI drop in average tire pressure, gas mileage can decrease by 0.2%. The department also claims that you can improve your gas mileage 0.6%–3% by inflating tires to the proper pressure. So, if your vehicle gets 32 MPG, you could improve your fuel efficiency by .192–.96 MPG just by airing up your tires. That may not sound like much, but it adds up!

Contrast this data with observations made by others here, indicating that high efficiency tires made no measurable difference for their fuel economy.

My point: People broadly, and Government specifically, focuses on feel good action while substantial measures go neglected. The downside is possibly the financial cost to the consumer, and the impact this tire regulation will have for those of us in CA with unusual tire size requirements. It's hard enough finding the right fit as it stands.

Some people cannot except that California, under democrat leadership has been tanking the state for decades. Yeah, other states have problems unique to them, but California goes out of its way to lose business, jobs, the middle and upper classes.

Hell, we’re already in a population decline here, imagine if they stopped illegal immigration; our states population would plummet.
 
Will LE be exempt from the roster? Can a family member from out of state transfer me "off roster" tires? Do we think the secondary market will drive prices of existing tires up?

WTS: I have 4 like-new, pristine, off-roster Mashimoto ZX tires in fifth gen (EJ1) Honda Civic fitment. Have maybe 50 miles on them. Cleaned thoroughly after the one use. Very rare. $5,000. No lowballers, no offers, no trades. Not even body armor.
But do the tires come with a Spoon engine, T66 turbo, NOS, and MoTec exhaust?

the "observations" here are anecdotes though, they are literally meaningless because the data isn't here to compare. But both can be true, people should fill their tires and also we may see cost savings with regulations to force efficiency. We have seen it with other similar regulations especially with water, which is a perfect analogy. Like you could say "people can just take shorter showers and save water". And also regulating low flow toilets also saved a substantial amount of water. I've done a lot of water supply calculations for my work and when looking at projected usage for municipalities, even with population growth the water usage remains low because efficiency goes up. And it's 100% because of efficiency regulations. Will the tire thing work out? we will see but assuming it's bad without any data is silly because how would you know?

Most LRR tires have a 50-65k warranty just like the other tires. There is mention of safety in the regulations, you can read them yourself. Also, winter tires don't fall under this regulation.

it is all by design. like i mentioned before, california is part of the WEF's agenda
 
I can’t believe there’s still people who think CA government actually cares about anything except money.
 
Bro that's not part of the smog check I promise you, your TPMS will not cause you to fail smog.
Funny, because my last smog check I failed for that very thing & when I questioned the tester (who I've been going to for years) he showed me the computer checklist with that item. Because under-inflated tires affect gas mileage they are now mandating fully operational TPMS systems.

That type of thinking would require logic and intelligence

is all this why lake mead is running out of water and that the colorado river is in the same aspect? lake mead is less than 200 feet from dead pool. do you even know what that means for california? i am not sure about data even being accurate when it comes to the water regulations in california, i mean the fact that L.A has no water in the hydrants should speak volumes about all that. why not have a desalination regulation instead, that would solve all of california's water problems, along with actually reducing cost. but let us not talk about that because more EPA regulations and taxes are the answer, according to these california politicians
 
Bro that's not part of the smog check I promise you, your TPMS will not cause you to fail smog.
not yet anyways, but coming soon. that is another point. this will open the allowance for more regulations, this is how it works. it does not stop at one. more is always the answer

I don't believe you, that's not a thing and I can't find anything to corroborate it. The only regulation that I am aware of is that repair stations have to fill your tires when you bring in your vehicle. But nothing that would make you fail smog. You are straight up lying.
