We have had these tires on our 2008 Prius for about a year. They replaced the Goodyear Integrity tires that came with the car. Some observations, they are a bit stiffer in ride than the Goodyears but they also seem to handle better (turn in, cornering). They have good grip and stopping performance for this type of tire. The fuel economy is about the same as with the OE Goodyears. You can hear them if you try, but the average noise level is very mild. After 10k miles they show almost no wear, so I'm betting they will make good on their mileage claims (or get close to it). They have held up well to the abuse of our pothole stricken roads and took an impressively small amount of weight to balance. We haven't driven them in the snow so we can't comment on that. Overall I'd say they are a good match for a Prius.
