    Im trying to figure out what the sticky tires expression would be for Cinema 4D.   in Maya, its simply this.
     
    tire.rz = - (tire.tx * (360.0 / (2 * 3.1415)));
     
    where  tire is the object name, rz is Rotate Z, and tx is Translate X. please help, as I will also still try to figure this out as well.

    Probably something like this
    var tire = doc->FindObject("tire");
    var pos = tire->GetPosition();
    var rot = tire->GetRotation();
    tire->SetRotation(vector(rot.x,rot.y,-(Radians(pos.x*(360/(2*PI))))));
    Though I guess the rotation values will be to big. So I would only use the position for a smooth rotation.
    var tire = doc->FindObject("tire");
    var pos = tire->GetPosition();
    var rot = tire->GetRotation();
    tire->SetRotation(vector(rot.x,rot.y,Radians((pos.x))));

    hmm, seeing your expression I guess this (360.0 / (2 * 3.1415)); is for the conversion between degrees and radians.
    But it should be simply 180*PI, so tire.tx/180*PI for the conversion
    In COFFEE Radians() is available for the conversion though
