California panel approves efficiency standards for tires

The California Energy Commission has approved first-in-the-nation efficiency standards for replacement tires on passenger vehicles and light-duty trucks.

That could limit which tires are sold in the state.

CEC says replacement tires are historically less energy-efficient than original factory tires. Harrison Reilly, the commission’s chief communications officer, emphasized that factory-installed tires are engineered for mileage, but consumers typically lose efficiency when buying replacements.

“These cost-saving standards are designed to ensure that replacement tires are at least as energy efficient, on average, as tires sold on new vehicles,” Reilly told The Center Square.

He said 70% of replacement tires currently don’t meet the new standards, but noted that also means 30% already comply with Phase 2 standards, demonstrating the technical feasibility.

The CEC doesn’t expect standards to be met immediately.

“Tire manufacturers have over six years to improve the remainder,” Reil...
