Can I get my $1B in advance?

The rule is “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.” It would also establish a labeling system that gives tires a “leaf” rating

Efficiency in terms of rolling resistance. Apparently the stock tires are designed to maximize efficiency to get a better sticker MPG, but after that you're on your own.

Hope the California tire companies don't try to recoup that billy

LRR tires are a mixed bag. They've given me better fuel efficiency but haven't latest nearly as long. I just traded fuel costs for tire costs. And I don't necessarily mean per set either. If the tires wear out 25% faster then I can't imagine it being better. It may actually be worse, and not just monetarily. Brake and tire dust are pretty bad pollutants as well. At least to those living near busy roads.

I'm all for better and more efficient tires, but unless you're getting better fuel efficiency for the same durability, I don't see how this is any better.

And to their point of increased tire costs, being forced to make a shit ton more will certainly being the price down some. Right now there just isn't a huge demand so regular tires outsell them by a wide margin.

Exclusions to the new rules found here

Competition tires designed for motorsports

Winter-type snow tires

All-season winter performance tires

Used and retreaded tires

Deep tread tires

Tires designed for ATVs and other off-road vehicles

Large off-road tires for use up to 99 mph

Motorcycle tires

Temporary-use spare tires

Small tires with ≤13-inch nominal rim diameter

Limited production tires (<15,000 per year)

Tires sold for use on an emergency vehicle

High load index tires (122 or greater)

Tires not capable of sustaining speeds over 50 mph

Space saver tires

1B/39M works out to $25 per person per year. That seems negligible at best.

The problem with efficient tires is that they are often a very stiff ride and have poor grip. They are usually designed to coast well, and that makes them harder. It’s a trade off. It also doesn’t help that the current fad is tires with narrower sidewalls.

How about we add a tax to tires that scales exponentially with their width? Wide sports car tires and bro-dozer pickup trucks with flashy rims will be motivated to use a setup with less drag/friction for the sake of performance/vanity.

The rule also comes with exemptions including snow tires and those used in competition. All-weather tires are also excluded, but the state will track them, as that growing segment may be regulated in the future.

Wait, so winters and all-weathers are excluded.....so this is only for summer tires? At least thats what it seems for their total projected roll out through 2033.

I can't remember the last time I bought summer tires...

It won’t ever be enforced
