I had Ecopia tires on my 05 Prius, 09 Prius, and 16 Spark EV. Good mileage but garbage tire. Dry traction was OK but they are horrible in the wet.

I switched from Bridgestone Ecopia (185/65R15) to Bridgestone Turanza Serenity Plus (195/65R15) on the Prius and dropped from and average of 49.5 mpg to 44.2 mpg. The better grip and turn in was worth it though.

In the Spark EV I went from the Ecopia to BFGoodrich Advantage Sport A/S (195/55R15) and dropped from 4.6 miles / kWh to 4.2 miles / kWh.

I think that BFGoodrich is a good compromise between price, grip and rolling resistance. I have them the Astro and Sportwagen.
