| ...to discuss this in an intelligent manner. Hell, my grasp of physics is too weak to really explain this in detail, but I'll give it a whirl. puts on the beads of a tire is not enough to break that seal (which a human can do with an 18" prybar and maybe 200 lbs of force MAX) Wow. Torque = r X F 889 newtons of force (200 lbs) on the end of a .447 m (17.6" assuming you only need roughly a centimeter to pry the lip of the tire) lever would equate to over 40,005 newtons of force if the fulcrum were placed at the one centimeter mark. So you're really using over 8993 lbs of force to unseat the tire. Note: this was quick math, but you get the idea. but at the same time cause a cast metal drum to flex in a telescoping motion without cracking the base? All materials flex to some degree without permanently deforming. Hint: do the anti-sway bars deform permanently after every body roll? (the spokes act as a base for the drum-shaped wheel when considering the forces applied to the wheel and what direction they are applied in). I really have no idea what you meant by that, but something tells me you don't either. Not to mention all the flexing going on in the suspension bushings which would relieve force applied strictly to the wheel/tire assembly ...or the suspension flex could be storing kinetic energy which when unloaded causes *amplified* forces to be unleashed on the wheel/tire assembly. I'm sorry, there just is no way. Do the math, it is impossible. What math are you referring to? There HAS to be an engineering guy or student on this site tonite who agrees. I'm arguably both and I disagree. I think you guys are overestimating the strength of a tire's bead, and the amount of grip a tire will provide (which is force applied opposite to the force you claim will flex the wheel). I think you last a basic understanding of how cast aluminum responds to applied forces. The tire's grip on the road will be overcome long before a metal wheel flexes, and the vast majority of the time before a tire loses it's grip on the wheel. You're making some pretty bold claims, then telling us to "do the math" when you clearly have no mathematical basis for any of your argument nor do you have any concept of how materials react to applied forces. Please don't try to argue evidence that you presuppose into existance, it makes for a pretty silly discussion.
