Choosing the right tires for your vehicle is crucial for ensuring safety and efficiency on the road. With the increasing popularity of electric and hybrid vehicles, tire selection has become even more important. In this article, we will discuss the importance of tire selection and how California is taking steps to ensure that replacement tires meet efficiency standards.

California’s Efficiency Standards for Replacement Tires

The California Energy Commission (CEC) has been considering efficiency standards for replacement tires since November 2020. These standards aim to ensure that hybrids and electric cars sold with efficiency-focused tires consistently get comparable replacements. The CEC has recommended a minimum standard for rolling resistance and a rating system for replacement tires.

Rolling Resistance Coefficient and Rating System

The proposed minimum standard for rolling resistance is a coefficient of 9.0, which would apply to the sale of new replacement tires beginning January 1, 2026. A more stringent target of 7.0 would take effect on January 1, 2028. The CEC also proposes a rating system for replacement tires, ranging from one to five stars, with five being the most energy-efficient and representing the highest potential cost savings.

Cost Savings and Impact on EV Range

While low-rolling-resistance tires can cost more initially, consumers may save between $800 and $1,400 per set of four replacement tires over the life of the tires through increased efficiency savings. Tires and wheels can have a significant effect on the range of electric vehicles, making it essential for owners to choose the right tires to maximize their vehicle’s performance.

Automakers Supporting California’s Emissions Authority

A group of automakers is backing California in a legal challenge against the state’s emissions authority. This support highlights the importance of tire selection and efficiency standards in the automotive industry, as well as the need for regulations that promote safety and efficiency on the road.
