Here is what I for see as the problem. Lets take in consideration the pneumatic tire of a automobile. It spins usually 1500 rpm and is meant to travel at speeds 100mph. The rim of the tire is meant to seal at the bead just right and have a place where you can balance the tire. because not every rubber tire you get off the assembly line is the same one. Now lets look at the Andymark pneumatic wheels, They have a simple design with a rim a tube and the tire. teams are spinning these wheels at complete excess of what they were designed to do. these tires cant be balanced nor do they 100% seal to the bead. Now if a team were to just by the tire from andymark and scale down a CAD design of a real life rim and buy some weights from Napa or any other auto parts store. then you will get a properly balanced wheel.
