Replacement Tire Efficiency Program Proceeding

These savings were calculated with gasoline prices of $4.60 per gallon. At the elevated gasoline prices of mid-2026, the savings could be 25% higher than estimated here.

Benefits of Proposed Regulation

• Consumer Savings: The proposed regulation would save nearly $1 billion per year in gasoline and electricity costs, putting money back in the pockets of California drivers.
• Air Quality: By reducing fuel consumed, the proposed regulation would reduce CO2 emissions by 2.0 million metric tons per year, which is equivalent to taking ~400,000 gasoline cars off California roads. It would also reduce other criteria air pollutants such as nitrous oxides and particulate matter.
• Reduced Energy Demand: The proposed regulation would reduce California demand for gasoline by 141 million gallons. It would also reduce demand for electricity by 0.9 TWh each year.
