Contact patch vs. tire width
Physics is not my strong subject, so any comments will be appreciated.
if a box and a ball are both 10" wide
the box would put a 10" contact patsche on the grounf while the ball would only put about a 1" contact patch on the ground.
while not really quite as extreme as the example above the shoulder of a tire (area where the tread meets the sidewall) can be very squared of like a box or very rounded like a ball.
