New replacement tire regulations have been passed by the California Energy Commission. The rules target rolling resistance to increase vehicle range for both gas and electric vehicles. Industry leaders have expressed concerns about the impact of these regulations, warning that they will phase out a significant portion of current tires.

The phase-out is expected to affect around 70% of current tires, which could lead to higher upfront costs for drivers. Further details about the new regulations and their potential effects are available from the source.

The regulations aim to boost fuel economy, but the exact implications for drivers and the industry are still being assessed. More information can be found through the original source.
