Published tests of these tires are rare. And another problem is that after a test emerges, the tire models change and we are in the dark again. I use Michelin Defenders and love them. Others ride on the Bridgestone Potenzas and love them. Look at brand new EVs and hybrids for the tire models they are rolling on. Given the pressure for high FE to meet govt standards, those new OEM-installed tires are probably very low rolling resistance.
