California tire rules may shrink budget options and raise costs
California regulators approved replacement-tire efficiency standards to boost energy savings, setting rolling-resistance limits at 9.1 N/kN in 2029 and 7.2 by 2033. While the Energy Commission projects small per-tire cost increases and fuel savings, industry voices warn many budget tires could be phased out, reducing choice and potentially raising prices for everyday drivers. Critics also worry lighter, more efficient tires could affect safety, especially for households already struggling financially.
