Hankook Dynasty RF03 were OEM on my wife's 07' Edge, and they are a great tire. I can agree that they are quiet and last a while without frequent rotations. We originally leased the vehicle for 3 years/45,000 miles, and the vehicle overall exceeded our expectations. We bought out the lease around 47,000 miles, and last Dec. with 52,000 miles replaced the back two tires which were shot. I think we had only two or three rotations done. I had the tech put the two new Hankook Dynasty on the front, and rotate the front to the back. Now at 61,000 miles the other two tires now need replacing. I know that the Ford dealer is a little pricey -- about $162 + $20/each mount/balance. NTB has them for approx. $15 less, and Mr. Tire sells them also (I think). Definitely worth getting.
