Colliders won't work

Hey,
Im making Android Racing game, everything is okay, but wheel colliders doesn’t work… I mean when you start a game my car goes through terrain until it reaches car body colliders, box colliders works perfectly, but wheel colliders won’t work at all… Any ideas why?

have you set the wheels to Is Trigger=true ? That would cause the behavior you describe?

Everything is triggered to true
