I bought these tires to replace the Kumho Ecsta's that wore out after just 30,000 miles. We went on a vacation the week we bought the tires and after 1000 miles of mixed driving in a one week period I could not be more satisfied with this purchase. The Ecsta's were very noisy, not a issue around town but after 5 hours at 80MPH it became very tiring, the P7's on the other hand were very quite and after driving 300 miles non-stop there was no noise induced fatigue. The rolling resistance on the P7's is so low that I also picked up 4MPG combined. The one complaint that I could have about the tires is actually a great complement, they took a little time to get used to as the turn in is much sharper and there is very little push in hard corners. I truly can not believe that a tire with a 700 treadwear rating can perform this well, I can now understand why it is rated at #1. I am looking forward to the next 60,000 miles to see how these do in the day to day.
