汽车的燃油消耗与克服轮胎的滚动阻力有部分关系,而克服滚动阻力所消耗的车辆可用功率多达三分之一,这意味着单单是轮胎就占了车辆油耗的20%～30%。与这种消耗相伴而来的是付出了环境代价。由此产生的与全球气候变暖相关的温室气体(GHG),是人为排放的二氧化碳的最大单一来源——它相当于人类产生的温室气体的60%左右。车辆所造成的污染多达25%来自 The fuel consumption of a car is partly related to overcoming the rolling resistance of the tire, and as much as one-third of the power available to the vehicle in overcoming rolling resistance means that the tire alone accounts for 20% to 30% of the vehicle’s fuel consumption. Accompanied by this consumption is to pay the environmental costs. The resulting greenhouse-gas (GHG), associated with global warming, is the single largest source of anthropogenic carbon dioxide emissions - about 60% of the human-generated greenhouse gases. Up to 25% of the pollution caused by vehicles comes from
