After 5yrs and 43kmiles I have approx. 10k miles left: I regard this as an extraordinary result on my Subaru (which I bought new and now has 127kmiles total). Prior to the Primacy, I tried many brands, including Bridgestone, Continental and a different type of Michelin, and never achieved more than 23kmiles. In addition, these tires have worn perfectly evenly: I give them a perfect 10 in treadwear. Comfort: while they are now harsher and noisier than new, overall noise is quite good and comfort good. My Subaru is certainly not a sports car, but both steering and directionality have improved significantly from prior brands. Overall, these tires were an excellent purchase and an outstanding value for me: I will almost certainly buy them again soon.
