As I visualize what you are doing, you are doing a tire circumference measurement using a smear of condiment, whose spread along the tire and subsequently the ground, could add or subtract a few centimetres either way to the circumference, dependent on how much condiment you use and how much it smears. The point being to be able to sit on the bike while rolling along, so as to accurately depress the tire as if you were actually riding.
And this is accurate how ?. I probably should ask, how accurate do you expect this to be ?
