I own a 2017 Prius Prime, and up to now have stuck with the tires the car came with (Toyo NanoEnergy A29). These get excellent mileage, but they're pretty darn noisy, and ideally I'd like to find a tire that provides a quieter ride. I'm curious what tires other Prius Prime owners have tried and how you liked them? And did you notice a major difference in mileage? TIA
