I am trying to understand all of the forces involved in a vehicles wheel, The weight of the auto on the wheel downward would be radial load, and the force 90 degrees from that would be the thrust load directly perpindicular with the wheel. What I learned is that there is an equal reacting force in the direction of each force so all of the forces should cancel out.
But you also have the tire, which is not rigid and is often described as a ring of short compression springs each tire having a different spring coefficient. And most of the rolling friction is from the tire I am assuming, and also assuming that the friciton in the hub and bearings in negligible unless it is all wheel drive where it is connected to the drivetrain.
I just wanted to check and see if I am missing something, and generally what is creating the motion when on a negative inclination where the vehicle is free rolling downhill essentially. Gravity is the dominant force, however is there anything else.
Any suggestions would be appreciated
