- lukan 2y agoYes, because rubber and asphalt do not really have a smooth surface unlike polished steel. So all the little bumbs give your car grip, but also cause friction, which is noise. One of the reasons, why trains are better suited in theory for long distance transport, than trucks. Little friction, so more energy efficient.
