California Becomes First US State to Set Efficiency Rules for Replacement Tires
Regulations That Would Block Sale of Older Tires Praised by Environmental Groups Amid Rightwing Backlash

TL;DR
- California is the first state to require energy-efficient replacement tires.
- The regulations aim to reduce vehicle emissions and lower fuel costs for drivers.
- The first phase of the standards begins in 2029, requiring replacement tires to be at least as efficient as those on new vehicles.
- The California Energy Commission (CEC) estimates annual savings of nearly $1 billion for drivers and a reduction of 2 million metric tons of CO2 emissions per year.
- Environmental groups praise the regulations, while some industry groups and conservative outlets criticize them as an overreach and cite concerns about increased tire costs.
- Michelin supports the regulations, deeming them technically feasible, while other manufacturers like Goodyear and Yokohama have raised objections.
- The CEC argues that the incremental cost increase per tire is low and will be offset by fuel savings.
- The regulations are seen as a significant move by California, especially given federal opposition to its green transportation measures.
