California Passes Restrictive Replacement Tire Law In The Name Of Efficiency

Key Points:

• The California Energy Commission has unanimously approved a mandate requiring most replacement tires sold in the state to match the low rolling resistance of original factory tires, effectively reducing tire options as 70% of current tires don't meet this standard.
• Exemptions exist for certain tire types such as used, motorsports, snow, motorcycle, and large off-road tires, but the majority of drivers will face a more limited and generally more expensive tire selection.
• The commission claims the higher upfront tire costs ($1.50 to $6.50 more per tire) will be offset by significant fuel savings, estimating $179 saved in gasoline over the tire's life based on California's higher gas prices, though some experts and tire manufacturers like Goodyear dispute these savings and cost estimates.
• Critics argue that low rolling resistance tires often have shorter lifespans, potentially negating fuel savings with more frequent replacements, but the CEC counters that their data shows no correlation between tire efficiency and durability in California's market.
• Starting in 2029, tires sold in California must meet rolling resistance limits that tighten further in 2033, potentially influencing other states to adopt similar standards; a new optional "leaf" rating system will help consumers identify tire efficiency, though it may not be consistently displayed by manufacturers.
