i have actually noticed an increase in grip in the dry but was told that the most noticeable place to pick up on the heat cycling is the wet as the tire is cold and hard and will be even less effective. probably just me trying to rationalize my spin. couldnt be driver error!
i have 9 days on my ad08s and still have a lot left which is pretty good wear. i rotate side to side and front to rear every couple days to maximize wear.
