I am trying to develop an understanding of the forces within a tire when moving. I have been told to examine the tire as a ring of short compression springs, so I would assume each tire essentially has a spring coefficient and spring rate. I don't imagine the tire manufacturer's give this in their specs. So how would you go about determining the forces involved in a tire as it goes down the road, relating with temp, pressure, speed, road quatlity, and of course the tire stats. Just recently I realized actually how much is going on within a vehicles tire, and have become fascinated in determining mathematically what is happening within. Any Help would be appreciated.
