right contact for my simulation?

The load is applied on center portion of the wheel.

A static simulation to find out the location of max stress, If the top wheel material is plastic and the bottom one is any harder material. using different contacts like bonded,

no penetration contacts the max stress location is different. So ultimately trying to perform fatigue analysis( the real case is not only a rolling contact fatigue, but it has a bumps, that means the wheel pass through bumps) is No- penetration(friction less and Node to surface) contact is the exact representation of the simulation (as i mentioned bumps) or bonded contact? In my view the max stress should be in the weaker area of the geometry but not at the contact location
