UE4 PhysX Wheeled Vehicle | Wheels fall through floor

Hey all,
Slight problem today, and I know this UE4.25 so I don’t really expect anything, but for whatever reason. The collisions on my wheels (though set properly according to the pxvis collision 1 command) fall right through the floor. The asset was made in blender and did have its scale and rotation set before export in addition to setting unit size to CM. I have a few photos if they help. But please let me know if you guys have had issues like this in the past and what you did to solve it.






Thanks!
