轮胎是汽车上最重要的组成部件之一,
支持车辆的全部重量,并传递其他方向的力和力矩;保证车轮和路面之间有良好的附着性,以提高汽车的动力性、制动性和通过性;保证行驶的安全性、稳定性、舒适性和节能经济性。
在日常生活中因为各种原因需要更换轮胎。最理想的都知道是四个轮胎一起更换,但这明显是最不经济的一种做法。那么我们如何选择才能经济又安全呢?
1,同轴轮胎建议花纹一致就可以,保证在高速状态下受到的摩擦力一致,有利于安全驾驶。(图为原厂胎和更换胎对比)
2,气门嘴也要更换,因为,当你更换轮胎后,新的轮胎和气门嘴的老化周期不同,在新轮胎周期内,气门嘴可能会出现问题,而这不容易被人们发现,所以最好在更换轮胎时同时更换气门嘴。
3, 安装方向和充气,如果使用的是原车配胎的话,要按厂家要求安装,如果是非原装轮胎,一般是带有生产日期的那头朝外,假如是方向性轮胎,则使车轮上的箭头与汽车前进方向相同安装。充气时可充致轮胎允许的最大气压,然后再降至厂家规定的标准气压。
4, 新的轮胎最好安装在车辆的后轴,如果把磨损比较多的轮胎放在车辆后轴,会减少后轮的排水能力,从而增加了雨天行驶的风险,所以如果只安装两个新轮胎,应按在后轮上。
5, 更换新胎后不要过急刹车,因为新胎花纹较深、胎毛较多,而且与地面没有充分磨合,过急刹车会影响车辆的制动效果,最好在新胎更换后的150km内不要过急刹车。
6,卸胎时对角线的方式卸掉螺丝,卸螺丝时一点点松,且用对角线的方式逐个卸掉螺丝,大致是1、3、4、2的方式卸。
注意

注意要清洁轮辋
润滑时不要使用汽油、机油、煤油
不要忘记检查气门芯、气门嘴基座、轮辋
当然,换胎时还应具体情况具体分析,详细咨询专业人员,确保安全最重要。
最后考验一下大家的眼力,下面十个轮胎只有一个轮胎的花纹是与众不同的,你能找到吗?
