车况不佳造成的油耗增高轮胎压力下降。行驶中的轮胎,它的气压会因时间的推移而有微小的泄漏,每过一个月轮胎的正常泄气量约为2KPa,这微小的压力下降,即会使汽车行驶油耗增大约2%—5%。由于这种气压的下降是逐渐出现的,不会在轮胎外形上有任何变化,乘坐的舒适感也不会有任何改变,但油耗 Poor fuel consumption caused by poor condition Tire pressure drops. Driving tires, its pressure will be slightly over time due to leakage, every month, the normal tire deflated about 2KPa, this slight pressure drop, which will make the car driving fuel consumption increased by about 2% -5 %. Because of this pressure drop is gradually emerging, there will be no changes in the tire shape, riding comfort will not have any change, but the fuel consumption
