Wheels Rotate or Turn, but not both

Hello!

I have problem with my wheel rotation. It works if I just make them rotate or if I just make them turn, but not both at the same time! What am I doing wrong?

public Transform wheelFLTrans;
public Transform wheelFRTrans;
public Transform wheelBLTrans;
public Transform wheelBRTrans;

void FixedUpdate ()
	{
		// Wheel rotation
		wheelFLTrans.Rotate (wheelFL.rpm / 60 * 360 * Time.deltaTime, 0, 0);
		wheelFRTrans.Rotate (wheelFR.rpm / 60 * 360 * Time.deltaTime, 0, 0);
		wheelBLTrans.Rotate (wheelBL.rpm / 60 * 360 * Time.deltaTime, 0, 0);
		wheelBRTrans.Rotate (wheelBR.rpm / 60 * 360 * Time.deltaTime, 0, 0);

		// Steering rotation
		wheelFLTrans.localEulerAngles = new Vector3 (0, wheelFL.steerAngle * 2, 0);
		wheelFRTrans.localEulerAngles = new Vector3 (0, wheelFR.steerAngle * 2, 0);
	}

Its because you are setting the steering rotation directly. Basically ona simple level you are doing this:

float x = 1;

x *= 5;    
x = 3;

Its the localEurlerAngles that is your culprit here. To fix change it rotate as your other lines do and convert your steer angle from degress to Radians (Mathf.DegtoRad)
