The tyre pressure is partly caused by the vertical load which you give at 5 kN. But it also depends of the initial inflation which can be considerably higher than the additional tyre pressure caused by vertical loads.
Even if I disregard that fact, the areas that are exposed to tyre pressure and contact pressure are not of the same size. So your assumption that tyre pressure and contact pressure are equal or near equal are simply false.
how can they be different? the pressure in the tire is the same everywhere and if the tire stiffness is negligible there is nothing to hold up the 5kN except pressure times area
