Hold on to your lug nuts guys, they're trying to ban your offroad, all terrain, and all season tyres...

https://www.energy.ca.gov/news/2026-08/cec-approves-nations-first-replacement-tire-efficiency-standards-saving

No doubt, Nevada and Arizona tyre shops are wringing their hands at the influx of business. 

 

And reading the article, fucking Michelin supports this.

The same Michelin (BFG) that shut down American manufacturing, and high tailed it back to france.

Just dropped $2,000 on new FalkenRT offroad rubber, and alignment. 

BFG wasn't even considered as a choice.

So this is how they intend to offset the excess tire wear associated with EV's.

A solution in search of a problem. Simply slap on a new set of Michelins, to the tune of $1,200 - just to save $179 in fuel over the life of the tires (quoted from the article). The "Fuel Efficient" O.E. tires that come on new cars dont last worth a damn. Furthermore - why wouldnt California want the tax revenue from the gasoline being sold?

It sounds like a ‘workaround’ would just be to supply the OEMs with the same tire sold to the public. Or maybe make them completely different models so that there’s no OEM ‘version’ to baseline it with and it wouldn’t need to match. 

I think that the measure is well meaning, but it probably should have just been a tire rating system instead of a mandate like this. Have an efficiency rating on the tires and let the consumer decide whether they want to choose the one that should theoretically give them the highest MPGs. Maybe eliminate the duplicate tire designations between OEM tires that are built to improve MPGs and the consumer tires that are not identical to those. 

This sounds like ‘well intentioned’ action that could/should have been handled better with less of a mandate than it is.

Or.... what if everyone in the whole state said no we're not doing that, I'll buy tires in another state, drive wherever I want, and not pay any extra fees or fines you try to charge us. Fuck you, arrest us all. Go ahead and try.

Ain't it nice that we have states that don't operate in a totalitarian manner such as CA?

Alternatively, if the entire country moved to the CA model, they'd start mass-shooting us in the streets as has happened with every other authoritarian regime.

You can bet your ass that skinner, the woman gavin put in charge of this,  drives a Prius with tyres just about that size. Only narrower.

There is a BIG exclusion list. Anything 10ply or greater is excluded. Some 8ply tires also can hit the 122 load index. Lots of light truck tires also are speed rated Q (99mph) so those are excluded from the regs too depending on what the definition of "large off road tire" actually is.

  • 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

Policy driven by, feelings over facts.

I have just skipped over this on bladed angels yt video. 

As i understand it they want low friction (aka traction)/low fuel consumption tyres... my question is if you lower friction/rolling resistance doesn't it also mean you elongate stopping distance of the car? You can't have cake and eat it too. So basically sacrificing safety for miniscule co2 emission reduction.

Feel free to correct my assumption of foreign vitard.

More "save up to 2% on carbon emissions while China triples their carbon footprint" BS. Fuck California. I am seriously going to circumvent as many laws as I possibly can.

As if that state doesn't have enough serious problems that need to be addressed.

Not that I didn't believe you, but I researched the same exclusion list.

That's quite a list of exemptions. 

Almost to the point of making the entire law a big waste of time and money. 

But then that's just exactly what that state is infamous for.

Who here needs tires anyway? They're building us a high speed rail system. 🙄

They already look like that. Small tires on a lifted truck has somehow become the "normal" look.

Meanwhile checkout the giant MPG strides Toyota has made in the last 40 years. City / Hwy
1986 2wd Tacoma - 21 / 25. 
2026 2wd Tacoma - 21 / 26. 
A whopping 1 MPG increase on the highway.  

Versus a1986 2wd Isuzu turbo diesel - 35 / 44 🙄

The only “Green” this country cares about is the green that goes in their pocket.

They’ve apparently never taken a mountain pass or rocky forest service road on stock tires. Guranteed flat with most stock truck tires.

Oh here’s another fun fact about the 40 year old 40+ MPG mini truck we can’t buy here anymore. They came with an almost 8’ long bed (7.7 feet). I’m dead serious when I say every person in this whole state needs to stand together and say fuck you, you clueless over educated beyond your intelligence dumbass brainwashed dipshits, NO, we’re not playing by your stupid tire rules, and we don’t care what tires are exempt or not. GTFO of here.  As a 67 year Ca resident I’m about out of patience with these zombie head in the sand decision makers. IMG 7260 1IMG 7261 2.jpeg?VersionId=HFzqTkaCHYs9EC2G9gUGj6BPlqbld

Michelin has stopped making tires in the USA? Thats odd since there factory’s are close to me in SC.

wish that could happen, but it so was frustrating to us getting hammered with new stupidity and lies every day- we just decided to switch rather than fight while we were still able bodied and could pull off a big relocation. Stress will kill you over time...

the people that get appointed to these boards and commissions with outrageous pay and benefits occasionally have to show some work output to justify their existence. Logic or quality of work output is irrelevant.

lol. They also managed to kill the effort by a successful private high speed rail company called Brightline that operates a successful high speed rail line in Florida that was ready to break ground on a new Barstow to Vegas high speed train. Forced the company to "partner" with the state and guess what happened?

You’re gonna see “All Terrain” tires with the LRR rating…I believe BFG & Yokohama already have them.

I guess it’s a good time to have a NV address? 🤣

California, with alllllll the legitimate problems that they have & yet they’re focused on shit like this?

Arnold must have crapped on somebody's sofa. It will no longer stop at Pixley.
