This is what keeps the tire within the edge of the wheel. It simply has no place to go. Next they add non-stretch cords to maintain the shape under pressure (carcass)... and all this is molded into the rubber along with the tread.</P><P></P><P>Bearings are somewhat specialized and come in several flavors. Best to do a Google search on "bicycle wheel hub" to get some ideas on how they are made.</P><P></P><P>Spokes are also interesting as the bicycle actually "hangs" on the vertical spokes on top.</P><P></P><P>Spokes bicycle wheels really are interesting from an engineering perspective. The more you look at them, the more you learn to appreciate them.</P></BODY></HTML> Sat, 09 Nov 2013 08:31:41 GMT https://www.ptcusercommunity.com/t5/3D-Part-Assembly-Design/How-does-rim-holds-Tyre-in-wheel-assembly/m-p/99032#M11037 TomD.inPDX 2013-11-09T08:31:41Z
