Small objects colliding problem ("sink" in terrain).

I’m making simulation for my three wheeled robot, and i need to keep original size. My robot have diameter 15 cm and mass around 0.2.

When i hit “play”, i’ve got this effect:

My object is not falling through terrain, but it sinks a few cm, and because that, the wheel colliders are not working properly. I know i could rescale the whole world, but i rather would like to avoid that. Is any way to edit terrain or some option in Unity, to make colliding more precise?

If this robot is an important role in your game I would increase the collision detection (requires using a rigidbody), search the docs for further info! Increase the scale of the collider of the robot, or offset the terrain collider a bit so it stands out the terrain. Try some of these options!
