This makes California the first state to regulate tire rolling resistance, often described as the squish of the tire. The measures aim to reduce fuel consumption regardless of a vehicle's overall efficiency. Proponents claim the new efficiency standards could save drivers $1B a year in costs.Why it mattersTires impact fuel economy through rolling resistance. By restricting low-efficiency replacements, the state attempts to lower emissions and costs without mandating
