How Can I Know which collider has call OnCollisionExit() on the script's gameObject??

In Code I Have Writed. im trying to know my plane have landed. then i need to know all my wheels is Ground. but i need to do it like this :

     [SerializeField]  // for see whats going on
     private List<bool> inContact = new List<bool>();
    
 
     [Header("Options :")]
     public List<Collider> Wheels;
     // Will Set it From inspector.
 
     void Start()
     {
         foreach (Collider col in Wheels) inContact.Add(false);
     }
 
     private void OnCollisionEnter(Collision collision)
     {
         if (Wheels.Contains(collision.contacts[0].thisCollider))
         {
             inContact[Wheels.IndexOf(collision.contacts[0].thisCollider)] = true;
             // Knowing That Wheel is inTouch.
         }
     }
 
     private void OnCollisionExit(Collision collision)
     {
         if (Wheels.Contains(collision.contacts[0].thisCollider))
         {
             inContact[Wheels.IndexOf(collision.contacts[0].thisCollider)] = false;
             // Trying To Know That Wheel Take-Off
         }
     }

This is not working because collision.contacts.Length is 0 at OnCollisionExit. Then This way cannot help me, But i need To know which MY collider called OnCollisionExit function because this plane have too much Collider and i just need wheels...

(After Edit)

I Did What i Want.

This Code For Landing Areas:

 public class LandAreaScript : MonoBehaviour
 {
     private void OnCollisionEnter(Collision collision)
     {
         if (collision.gameObject.tag == "Player" && collision.gameObject.GetComponent<PointSystem>() != null)
         {
             collision.gameObject.SendMessage("GetLanded", collision.collider);
         }
     }
 
     private void OnCollisionExit(Collision collision)
     {
         if (collision.gameObject.tag == "Player" && collision.gameObject.GetComponent<PointSystem>() != null)
         {
             collision.gameObject.SendMessage("GetTakeOff", collision.collider);
         }
     }
 }

And This for my plane:

 public class PointSystem : MonoBehaviour
 {
     [SerializeField]  // for see what is going on
     private List<bool> inContact = new List<bool>();
 
     [Header("Options :")]
     public List<Collider> Wheels;
     // Will Set it From inspector.
 
     void Start()
     {
         if (Wheels.Count == 0) this.enabled = false;
         foreach (Collider col in Wheels) inContact.Add(false);
     }
 
     public void GetLanded(Collider Input)
     {
         if (Wheels.Contains(Input))
             inContact[Wheels.IndexOf(Input)] = true;
     }
 
     public void GetTakeOff(Collider Input)
     {
         if (Wheels.Contains(Input))
             inContact[Wheels.IndexOf(Input)] = false;
     }
 }

It is working now. But at other projects

Am i need to Set this LandAreaScript to all objects???

No way to do That. Will not Optimize.

I Get Dissappointed by Unity.

WHY THERE IS NO WAY TO GET COLLIDER which one at same object with script?

We need a Read-only variable at Collision Class like "thiscollider".
