California is reviewing efficiency standards for replacement tires, helping to ensure that hybrids and electric cars sold with efficiency-focused tires will always receive comparable replacements.
As noted by the trade publication Modern tire dealerPerformance standards for replacement tires have been discussed for some time, but may move closer to implementation after data collection by the California Energy Commission (CEC), the sub-regulatory agency. responsible for drafting the proposed standards.
The CEC has previously been granted the authority to adopt and implement tire performance standards through legislation, and it introduced data collection campaign in November 2020. Earlier this month, they proposed a minimum standard for rolling resistance, along with a rating system intended to help consumers compare the relative performance of replacement tires.

The minimum standard will be a rolling resistance coefficient of 9.0, which the CEC says is the current industry standard, which will apply to sales of new replacement tires starting January 1, 2026. The target is more stringent. is 7.0 will come into effect January 1, According to CEC, these targets will not be allowed to interfere with wet traction or other safety standards.
CEC also recommends a rating system for replacement tires, ranging from one to five stars, with five stars being the most energy efficient and the highest potential cost savings. While tires with low rolling resistance can be more expensive, California also says: “Consumers can save between $800 and $1,400 per set of four replacement tires over the life of the tire through savings. efficiency increases.”

California has committed Ban on the sale of new gasoline-powered cars (not very efficient plug-in hybrids) by 2035, and these standards can help support that goal.
Tires and wheels may have greatly affects the EV . range, which is why most electric vehicles leave the factory with low rolling resistance tires focused on performance. Electric cars too need different tiresfor a number of reasons such as extra weight and the need to mask tire noise that would otherwise drown out the internal combustion engine, so making sure similar replacements are available will be important .
Group of car manufacturers supporting California in a legal challenge against the state’s emissions agency, so it’s possible they’ll also support these tire standards.
