Re: bead and sidewalls ......Think of it this way…

Picture you in your car as you are driving. Now picture your right front tire as your hard in a left turn. That tire is trying to hold traction as the weight of your 3500lb car is pushing towards the outside of the turn. If you turn too fast your tires will break traction and the car will slide, correct ????
Now picture what is really going on there. That tire is putting incredible stress on the sidewall and bead to keep the tire from rolling off,, or under the rim.
A motorcycle tire in that same left turn has completely different effect. The weight of the motorcycle is pushing down on the tire at the same angle the motorcycle is leaned at. The outside bead is NOT taking the same stress that your 3500lb car puts on that same tire in the same turn.


Maybe I am totally off here and the real experts can shed a bit more light on the subject but this is what my experience and research showed me when I was looking into Car tires years ago…
