California Passes Restrictive Replacement Tire Law In The Name Of Efficiency

Key Points:

• The California Energy Commission has unanimously voted to require most replacement tires sold in the state to meet the same low rolling resistance standards as original factory tires, significantly reducing tire options since 70% of current tires don't comply.
• Exemptions exist for certain tires like used, motorsport competition, snow, motorcycle, and some off-road tires, but the majority of drivers will face a limited selection of more efficient, yet more expensive tires.
• The CEC claims the higher tire costs ($1.50 to $6.50 more per tire) will be offset by fuel savings of about $179 over the tire’s life, based on California’s higher gas prices, though critics like Goodyear argue costs could be much higher and question the data on tire lifespan and cost savings.
• The new tire rolling resistance limits take effect in 2029 and tighten further in 2033, potentially influencing other states to adopt similar standards, while a voluntary "leaf" rating system will help consumers identify tire efficiency.
• Critics highlight concerns over reduced consumer choice and potential increased overall costs due to possibly shorter tire lifespans and higher prices, despite public hearings, Californians did not vote on these regulations.
