These are the new Nankang CRS V2 tires (P325/30/R20) with a 70+ laps being completed at Daytona the week before and another 30+ laps completed at Sebring before this lap.....I wonder what I could have hit with new sticker tires? The Garmin optimal lap says 2:19.5......these tires are amazing....they really grip and hold up under the most difficult track conditions at both Daytona and Sebring. Also, these are 200 treadwear tires that handle like a 100 treadwear tire.
