In trying to find good tires for EVs, the EU tire label is very useful. It's something the US should adopt. I have found I can find them on manufacturer's global websites. The left side (fuel efficiency) is a measurement of rolling resistance, a key factor for EV tires. As an example, here are the labels for the tires I have on my MINI Cooper SE: summer tires winter tires
"Global" being the key word here, as their U.S.-facing sites don't include this valuable information. Even so, you may not find the EU label for a model which predates the new label requirements. I also search these 2 sites when trying to find the EU label information for tyres I'm interested in: https://www.tyrereviews.com https://whattyre.com It's also important to note that the label values can be different for the same model tyre across different sizes, speed ratings, and load ratings. Runflat variants seem to always have the worst fuel efficiency rating, too.
