Von Mises Stress Results:The entire circumference of the inner rim exhibits stress of around 55MPa. This is interesting since you would expect the stress to be higher where the load was applied, this is not the case. This may be due to the FEA model where the tyre is rigid to the wheel (volume), a contact model may yield different or similar results - can't be deduced unitl it's done! The stress in the spokes is around 60-65MPa, but we do not know if it's tensile or compressive. There are high peak stresses around the circumference of the outer rim, most likely due to the rigid tyre model again. High peak loads can also be seen on the inner hub flange (rigid elements) - these stresses are not real since the rigid elements are connected via 'point to point', which over estimate stress.

Displacement Results: Maximum of 100mm - perfect since a spring rate of 100KG/cm and 10kN force gives 100mm displacement of the spring element. This means the entire load is being reacted through the tyre and wheel.
