California's Energy Commission approved the Replacement Tire Efficiency Program, creating the nation's first rules governing aftermarket replacement tires with exemptions for specialty tires; the plan is phased in starting in 2029 with stricter standards in 2033, and is expected to save drivers nearly $1 billion and reduce CO2 by about 2 million metric tons annually, amid mixed industry reactions (support from Michelin/Bridgestone, concerns from SEMA).
