WheelCollider is not round

I am making a physics based vehicle game of some sort but there is one problem that I can not solve. the wheel collider in unity is not round and when I try to drive my car on a cube it is very unrealistic.

If you have any idea how to solve this please post an answear

List of things I have already tried:

*Sphere collider with zero friction -suspenstion did not work.

*More wheel colliders rotated at different angles -the wheels shaked all the time and flew away when it hit something.

Sorry for bad English.

That’s exactly correct, the wheelcollider is not round because it uses raycasts to detect collisions. The gizmo is not representative of its collision. Many people implement custom wheelcolliders to solve physics problems and/or opimize performance.
