California just became the first state to approve efficiency standards for replacement tires.
Beginning in 2029, many replacement tires sold in California will have to meet new rolling-resistance and performance requirements, with stricter standards coming in 2033. While competition and certain off-road tires are currently exempt, the broader implications deserve the motorsports and aftermarket industry's attention.
Why does this matter? Regulations that begin with everyday replacement tires can influence product availability, manufacturing decisions, costs and consumer choice far beyond California. For the aftermarket, Motorsports, off-road and overlanding communities, this is another reminder of why staying engaged in state-level policy matters.
Today it's tire efficiency.
Tomorrow, what other aftermarket products could face similar standards?
