I just put a set of 4 new Michelin Primacy tires on my 2008 Prius. I got 42K on my original factory tires, Infinity's. I averaged 50-52 mpg as a rule and am anxious to see how the new Primacy tires do. If anyone else has put these tires on their Prius I would like to know what you experience.
I've had my Primacys for about 2000 miles now. I keep them at 44psi and have noted a 2 MPG drop from 59 to 57. However, it's worth it for the quiet, smooth ride.
My prius came with michelin primacy original from factory So far i love them, they are very quiet and im averaging 55 MPG
