How to rotate instantated prefab without rotating it's local directions by javascript?

I have created Wheel prefab. And instantiate it 4 times to get 4 wheels with one drawcall. Wheel have more datailed external side and less detailed internal side. During instantiation need rotate Front right and back right wheels - to make it's less detailed sides look inside. Rotation I try to do in 2 wrong ways:

 var fwStifness = 0.9;
 var swStifness = 0.25;
 var spring = 5500;
 var damper = 50;
 
 var Vehicle : GameObject;
 var Mesh_FL : GameObject;
 var Mesh_BL : GameObject;
 var Mesh_FR : GameObject;
 var Mesh_BR : GameObject;
 function Start () {
 Vehicle = Instantiate(Resources.Load("IS200-prefab", GameObject),Vector3.zero, Quaternion.identity);
     Mesh_FL = Instantiate(Resources.Load("Wheel", GameObject),Vector3.zero, Quaternion.identity);
     Mesh_BL = Instantiate(Resources.Load("Wheel", GameObject),Vector3.zero, Quaternion.identity);
     Mesh_FR = Instantiate(Resources.Load("Wheel", GameObject),Vector3.zero, Quaternion.identity);
     Mesh_BR = Instantiate(Resources.Load("Wheel", GameObject),Vector3.zero, Quaternion.identity);
 //*********************************************
 //....here was unnecessary code for my question
 //*********************************************
     Mesh_FL.transform.position = Vector3(-0.7,0.32,1.33);
     //1st way
     Mesh_FL.transform.localEulerAngles = Vector3(0,180,0);    
     //2nd way
     //Mesh_FL.transform.RotateAround(Mesh_FL.transform.position,Vector3.up,180);
     Mesh_FL.transform.parent = Vehicle.transform;
     Mesh_FL.name="FL";
     Mesh_FL.AddComponent(WheelCollider);
     Mesh_FL.GetComponent(WheelCollider).forwardFriction.stiffness=fwStifness;
     Mesh_FL.GetComponent(WheelCollider).sidewaysFriction.stiffness=swStifness;
     Mesh_FL.GetComponent(WheelCollider).suspensionSpring.spring=spring;
     Mesh_FL.GetComponent(WheelCollider).suspensionSpring.damper=damper;
     
     //Mesh.FL.GetComponent(WheelCollider).suspensionSpring.damper=5500;
     
     
     Mesh_FR.transform.position = Vector3(0.7,0.32,1.33);
     Mesh_FR.transform.localEulerAngles = Vector3(0,0,0);
     Mesh_FR.transform.parent = Vehicle.transform;
     Mesh_FR.name="FR";
     Mesh_FR.AddComponent(WheelCollider);
     Mesh_FR.GetComponent(WheelCollider).forwardFriction.stiffness=fwStifness;
     Mesh_FR.GetComponent(WheelCollider).sidewaysFriction.stiffness=swStifness;
     Mesh_FR.GetComponent(WheelCollider).suspensionSpring.spring=spring;
     Mesh_FR.GetComponent(WheelCollider).suspensionSpring.damper=damper;
 }
 function Update () {
 Mesh_FL.transform.Rotate(10 * -6 * Time.deltaTime, 0, 0);
 Mesh_FR.transform.Rotate(10 * -6 * Time.deltaTime, 0, 0);
 }

On update this wheels are rotating in different ways (because their pivot directions look in different ways)

How can I rotate mesh of wheel prefab after instantiation without changing pivot direction? Thank you, and sorry for my poor English.
