Wheel collider works in editor, not on iOS

I have an airplane with a wheel collider. Works in the editor, but on iOS it goes straight through the ground and the plane lays on its "belly".
The collider is of reasonable size (airplane is real scale, 1 unit = 1 m), I decreased fixed timestep for all physics to increase physics precision, i made the collider extra large but nothing helps. Any tips?
In the attached screenshot, it's oversized obv.

 

The problem was that the environmentreflectionprobe from Ar foundation examples somehow got a negative scale, which affected its box collider, which apparently creates bugs with other colliders down the scene hierarchy.
