I resurrected two papers - in The Physics Teacher, not the AJP. Both
agree with Michael Edmiston:
1) "What holds up the steel wheels of an automobile?", W Shurcliff,
TPT, 32, pg 296, May 1994
2) "How do tubeless tires support an auto?", J Sperry and E Jones, TPT
32, pg 174, March 1994

||I remember discussions from years ago when a group of physicists
came

||
|| The bead is the area of contact between the tire and the wheel.
| That's
|| where the upward force of the tire is acting on the wheel. The
bead
| is very
|| strong, and nowadays has steel cable in it. The wheel is
| essentially
