This is what makes ADV so great! 54 pages of feeding the troll. I once had this conversation with a guy that mounted his own tires, who swore that no scrubbing in was ever necessary for him... He lived on a 1/4 mile loose gravel driveway. By the time he hit pavement, the tires were fine. It simply never occurred to him that he was scrubbing the surface by riding the gravel out to the road.
