M450 Steer Tire BlowOut

[GregOConnor]

I Wicked Scrub Radius http://en.wikipedia.org/wiki/Scrub_radius and have a bit more understanding. It seems that the discussion on all the king pin scrub radius, FIS has to do with control after a failure. I wonder what causes the failure. Does the design give more stress to one side tire in a turn then fail going down the road later?
My background is digging holes and I dont know much about the dynamics and geometry involved in this discussion but, has slow moving stresses been considered ? since the suspension is designed to add camber in turns and change scrub Radius for control what happens in a slow turn without the forces of inertia making these changes? could it be slow turns where the tire casings are being stressed?
