What Changed This Week
Dunlop Tires North America put its senior team in front of the industry on August 28 for a webinar walking through California's Replacement Tire Efficiency Program — president and CEO Darren Thomas, VP of marketing and product development Ken Hsu, and associate VP Rick Brennan. It was the most detailed look yet at how a manufacturer is actually planning around the rules, and Modern Tire Dealer covered it for the trade.
We sell a lot of Falken, which comes out of the same parent company, so we paid attention. Here's what stood out, translated out of industry-speak.
Compliance Isn't Free, and It's Not Just Rubber
The point DTNA's team kept coming back to: hitting a lower rolling resistance number isn't a switch you flip. It generally means more advanced materials, more complicated production, and a significantly larger validation testing burden before a tire can be sold at all.
That last part matters more than people realize. Under the program, tire makers and brand owners have to submit model and test data into a California Energy Commission database. A tire either clears the applicable standard or qualifies for an exemption — and until it's in that database and authorized, it isn't legal to sell in this state. That's a per-model cost, and it applies to every single SKU a company wants to keep on California shelves.
Now think about which tires that math punishes. A high-volume touring tire spreads that cost across hundreds of thousands of units and barely notices. A low-margin, low-volume budget model in an oddball size does not. Some of those simply won't be worth re-engineering and re-certifying.
The "Tier-Down" Problem
DTNA's executives also flagged something we see at the counter every week: customers have been trading down. Tighter budgets mean more people shopping the third and fourth tier instead of the second, and manufacturers have been building product to meet that demand.
Here's the collision. The tier that's growing fastest in demand is the same tier most exposed to the new standards. Bargain imports tend to score poorly on rolling resistance and on wet braking — and starting with 2029 production, tires have to clear a wet grip minimum too. That's a safety floor we're honestly glad to see, since it targets exactly the tires that scare us when they come in on a trade-in. But it does mean the cheapest end of the market takes the hit.
How much of the current lineup gets squeezed out by 2033 is the number everyone is arguing about — and we broke that fight down separately in Goodyear vs. the State: Whose 70% Is Right? Short version: both sides are reading the same data, and neither of them is lying. What nobody disputes is that the pressure is concentrated at the bottom of the price ladder.
What the State Says Versus What the Industry Says
Worth holding both of these in your head:
| Cost per tire | Position | |
|---|---|---|
| California Energy Commission | ~$1.50 (Phase 1), ~$6.50 (Phase 2) | Fuel savings outweigh the added cost several times over |
| Manufacturers & SEMA | Disputed as understated | Materials, process complexity, and per-model testing aren't fully priced in |
Our read hasn't changed since we wrote about this two weeks ago: six dollars on a mid-range tire isn't what will hurt Long Beach families. The disappearance of the sub-$70 tire is. That's the number we're watching.
The Part Nobody Has Answered Yet
Here's what's still genuinely unsettled, and DTNA's leadership said so plainly: at this stage, it isn't clear what shops and retailers will have to do to make sure the inventory sitting in their racks is authorized for sale.
Is that a lookup against the state database at point of sale? A supplier certification? A recordkeeping requirement on our end? Nobody knows. The regulation is written around manufacturers and brand owners; the practical procedures for independent dealers like us are still being worked out.
We're mentioning it because you'll hear noise about it over the next couple of years, and some shops will use that confusion to create urgency. There is no urgency. Whatever the compliance mechanics end up being, they're our problem to solve, not yours — and they don't start until 2029 production reaches the market.
What Actually Affects You in Long Beach
Buying tires in 2026, 2027, or 2028: Nothing changes. Buy what you'd normally buy. Don't let anyone tell you there's a deadline.
Buying the cheapest option available: This is the group to watch. If your budget lives at the bottom of the board, the entry price for a set is more likely to move up after 2033 than before it. That's four to seven years of runway, not a reason to panic-buy.
Running a work van, fleet, or 3/4-ton: Commercial C-suffix tires got folded in alongside LT tires in the final rule. If you run fleet vehicles, the lines you buy are worth reviewing around 2028, not now.
Shopping used: Inspected used tires and retreads are exempt from the program entirely. That lane stays open, and we'll keep stocking it.
Driving an EV or hybrid: The new zero-to-four-leaf efficiency rating is going to make range shopping dramatically easier. For once, a regulation that hands you a real comparison tool.
Where We Stand
We've been putting tires on cars in this neighborhood since 2002, and family-owned since 1988. We've watched regulations reshape this industry before.
Our position on this one is the same as Dunlop's, honestly: nobody here is against cleaner, more efficient tires. A tire is a balancing act — rolling resistance against traction, tread life, load capability, ride, noise, and price. Push hard on one and something else gives. What we care about is that the something else isn't the ability of a working family in North Long Beach to put four safe tires on their car.
So our job through the next few years is straightforward. Work our distributors to keep a real value option on the board. Tell you the truth about what you're buying and what it'll cost. And when someone tries to sell you urgency about a 2029 deadline, tell you it's nonsense.

Frequently Asked Questions
Will cheap tires be banned in California?
No. The Replacement Tire Efficiency Program doesn't ban tires by price — it sets minimum rolling resistance and wet grip braking standards for tires manufactured on or after January 1, 2029, with tighter limits from 2033. The practical effect is that budget models scoring poorly on both measures may not be re-engineered for the California market, which could reduce the number of low-cost options available.
Why do manufacturers say compliant tires will cost more?
Tire makers point to three cost drivers: more advanced materials and compounds, more complex production processes, and expanded validation testing. Every model also has to be submitted to a California Energy Commission database and authorized before it can be sold in the state, which adds a per-model compliance cost.
Do tire shops have to do anything under the new California tire law?
The regulation places its requirements on tire manufacturers and brand owners, who must report model and testing data to the state. As of August 2026, the specific procedures independent dealers and retailers will follow to confirm their inventory is authorized for sale have not been finalized.
Are used tires affected by California's tire efficiency rules?
No. Used tires and retreads are explicitly exempt from the program. They remain legal to sell and buy in California without any efficiency or wet grip requirement.
Should I buy tires now before the California rules take effect?
No. The rule applies based on a tire's date of manufacture, not the date of purchase. Any tire built before January 1, 2029 remains legal to sell and drive on permanently, so there is no deadline to beat.
