You should be able to contact a seller and request the data for your tire options. ........
I don't think California ever finished the regulation. They got as far as requiring trucks to use SmartWay tires, but I don't think they got to the point where they mandated passenger car tire manufacturers to published rolling resistance information. I think they deferred to the Feds (NHTSA) and that regulation is taking a long time to work its way through the system. The last I heard, NHTSA was going to publish the regulation in August, 2018 with the end of comments due by Oct, 2018.
