until the initial ~500 miles are driven. The tire lubricants used in the mold definitely create a slick tire for the first few miles. Thats why I noted that I'm on about 400 miles on my set but I have a pretty good feeling they're broken in by the feel and how its changed since purchase. I also noted rolling into boost because I don't consider that hard acceleration. I feel pretty accurate in my statement that they fall in between the two tires I mentioned but I guess I'll see in another 100 miles if anything changes.
