俗话说千里之行始于足下,作为车辆的“脚”,轮胎对于行车安全可是起着至关重要的作用,因此对于轮胎的养护就显得尤为重要。轮胎作为车辆行驶中与地面接触的部件,发生磨损不可避免。轮胎的磨损主要是由轮胎胎面与路面之间的摩擦造成。生活中很多朋友喜欢自己动手检查爱车,但是有时苦于没有经验所以无从下手。而对于轮胎的自检来说并不难,检查的目的也很明确,掌握爱车轮胎的现状,判断是否需要更换即可。
1、轮胎老化
观察轮胎胎面以及胎壁上的纹路,如果普遍出现裂纹则表明轮胎已经老化严重。此时虽然行驶公里数不长或是使用时间不久,但是仍然需要及时更换。
2、磨损严重
每个轮胎胎面凹槽处都有一个磨损极限的标识,这个标识厚度大约2mm左右。专业的轮胎店建议,轮胎厚度磨损至距离极限标志4mm,也就是距离凹槽最深处6mm左右时就应当进行更换。
3、轮胎鼓包
轮胎出现起包变形是一件很危险的事情,如果发现起包变形的情况,最好第一时间去专业维修店进行检查处理,一般情况下都建议更换轮胎。轮胎出现此类情况证明轮胎内部的金属线圈已经变形或断裂,如果继续行驶则极有可能发生爆胎危险。
4、补胎次数过多
一般超过3次补胎就该重视了。对于轮胎被扎,很多朋友并不会太在意,路边修理铺二三十元的价格就可以修补完成。不过如果同一轮胎屡次被扎,能否频繁的补胎呢。专业人员向我们介绍,一两次的补胎不会影响轮胎的使用,但是超过三次之后,出于安全的考虑就建议更换轮胎了。因为当高速行驶时,轮胎内温度升高,多处损伤虽已弥补,但是仍然增加危险出现的几率。
轮胎是橡胶件,当然会正常老化。按照轮胎厂家的官方说法,一般轮胎的寿命应当在2年或6-8万公里区间。当然实际使用过程中,遵循这个规定我们的用车成本可就太高了。我们从专业人士处获悉,如果平时使用并不频繁,并且用车环境并不恶劣,最好是有车库能保证相对小的温差情况下,一般轮胎正常使用四五年是不成问题的,当然前提是勤检查,尽可能的小心爱惜使用,并且不出现以上五种情况的状态下。
以上就是轮胎对于行车安全可是起着至关重要的作用,如何判断轮胎是否需要更换的全部内容了,希望对您有所帮助。
