轮胎对于一台车来说是非常重要的,轮胎保护的好,从小处说可以帮你省钱,从大处说关系到生命安全,所以这篇文章,我来把我积累的一些关于轮胎保护的经验给大家分享一下。
由于内容比较零散,就不讲究结构了,想到啥说啥。
首先要讲一个非常重要的常识,轮胎的侧面最脆弱。
有些车友对轮胎的结构不太了解,其实汽车的轮胎都是跟地面接触的底面比较厚比较结实,而轮胎的侧壁都是很薄的,所以轮胎的侧面都很脆弱。正常来说,轮胎的底面都是有钢丝层的,而侧面不但薄,而且没有钢丝,只有线,所以一旦受到强大的外力挤压,容易把线弄断,从而造成轮胎鼓包报废。
有些不好的开车习惯很容易损伤轮胎。
比如在侧方停车的时候,有的司机非要把车停的距离马路牙子特别近,这其实就是一个不好的习惯,由于停的太近,隔三岔五控制不好就会把轮胎的侧面挤压到马路牙,对脆弱的轮胎侧面很容易造成损坏,一旦把轮胎侧面的线被太大的压力挤断了,轮胎就会鼓包,就废掉了。所以侧方停车的时候建议大家不要追求过近的距离,这样容易损坏轮胎侧壁。
再比如,有些人觉得,我虎八是SUV,底盘这么高,爬个马路牙子很方便也很威武,其实这也是一种不好的习惯,当你硬爬马路牙子的时候,轮胎受到的压力比平路大很多,一次两次的可能还无所谓,但是如果次数多了,就可能造成脆弱的轮胎侧面线断裂,造成轮胎鼓包报废。所以建议大家,偶尔遇到没地方停车上个马路牙子可能没事,但是一定要尽量减少这种操作的次数,能不上尽量不上。更何况,其实城市SUV因为本身就是轿车结构,频繁的上马路牙子也可能造成悬挂的变形和损坏。
另外,虎八作为一台SUV,底盘高,通过性比轿车好,所以很多车友可能开他去自驾游,走烂路,但是走烂路的时候一定要注意一个问题,就是要保护好轮胎的侧壁。比如说路上有那种灌木被砍断留下的尖锐的茬子,比如说有一些尖石头,这些东西都可能会扎破你脆弱的轮胎侧壁造成轮胎报废是小事,在荒郊野地轮胎爆了换胎可是要头疼死了。另外在越野路况有时候轮胎的侧面还可能挤压到侧面的土坡石头之类的,都是安全的隐患,所以要尽量跟这些东西保持距离。
还有就是,轮胎是用橡胶制成的,橡胶对于某些特定的化学物质是容易被腐蚀的,所以尽量不要在轮胎上使用一些性质不明的化学物质,各种什么轮胎保养剂之类的谁知道是啥成分,我个人建议尽量还是不要弄的好。
再比如,在路上可能会偶尔遇到一些比如掉落的砖头,石块之类的东西,尽量不要很快的速度去碾压,如果赶上那个寸劲儿,也可能损坏轮胎,还是那句话,损失轮胎是小,一旦造成人身危险事大。
另外一个,合理的胎压也非常的关键。胎压太高或者太低都有危害。如果你的胎压过高,轮胎就会过硬,这样会带来一系列的问题。
首先是舒适性下降,胎压合适的轮胎会有比较好的缓冲减震效果,而胎压过高的时候,减震效果就会下降,车就会比较颠簸,甚至在遇到坑洼的时候还会蹦起来,这样让人很不舒服,同时,胎压高还会造成减震器的负担过重,造成减震器的寿命减少,早早的漏油报废。另外一方面,胎压太低也会有问题,胎压低带来的好处就是减震效果更好,舒适性提升,但是胎压过低则会造成轮胎在滚动过程中长时间的折叠造成温度升高,同时也容易开裂损坏。所以保持合理的胎压很关键,我经过反复的摸索,同时也咨询了奇瑞4S的售后总监师傅,得到的信息是,虎八轮胎最合理的胎压是冷车2.3,这个胎压在你跑起来之后因为摩擦发热可能会增大一点,这都是正常的。
另外一个容易造成轮胎损伤的,就是比如有些城市里面突然出现的比较深的坑,这个是很容易中招的,在车速比较快的时候突然车轮掉进坑里面,对轮胎的冲击还是很大的,所以要格外注意这种路况,这时候因为车速快,轮毂的冲击很可能造成轮胎侧壁线断裂造成轮胎鼓包,另外极端情况下还可能把轮毂撞坏。因为虎八的轮毂是铝合金的,铝合金的特点就是比较脆,不会变形,但是容易撞碎破损。
另外,轮胎受到的另外一个威胁就是类似钉子这种尖锐物体扎胎,如果划伤了侧壁,这轮胎就废了,高速肯定是不能跑了,凑合开到轮胎店赶紧换掉,轮胎侧面如果破损是不能补胎的,因为效果很不好,所以只能换新的。另外虎八普遍都有胎压监测,如果是豪华型没有胎压监测的,建议也装一个,这样可以随时监控并保持合理的胎压,发现轻微的泄漏和扎胎的情况可以及时处理。
另外再给大家一个建议,不管是什么情况下,跑高速的车速都不要太快,车的危险系数是随着车速的增加而呈指数增加的。如果车速特别快的情况下,一旦发生爆胎,尤其是前轮爆胎,很大的几率会翻车,基本上人可能就完蛋了。
另外跟大家分享一个经验,我个人是遇到过爆胎的,如果是你的后轮爆胎,那情况还比较好处理,你会感觉车子突然动力下降一般的感觉,车身发沉,但是并不影响你的行车方向,这时候你就知道是爆胎。但是如果是前轮爆胎,那就危险的多了,车会发生跑偏,这时候最忌讳慌张猛打方向,很容易造成翻车,也不能紧急刹车,这时候合理的处理方式是双手全力抓紧方向盘稳住方向,同时不断的轻点刹车让车速降下来,车速慢了之后再尽快靠边处理情况。
另外在轮胎的选择上,大家也要知道一些前提。轮胎的舒适性当然是胎宽越大越好,原因很简单,一个是轮胎跟地面的接触面积大了,稳定性更强,再一个,比如遇到路上有小坑,如果你的轮胎足够宽,那你可能就直接把这个小坑覆盖住了压过去了,可能根本就没有感觉,而轮胎比较窄的话可能车轮就会掉进坑里面去,使劲颠一下。但是宽胎也会带来一个大的问题就是摩擦力增大,从而造成油耗增加,所以大家在更换宽胎之前一定要考虑到油耗增加的因素,从而做出最合理的选择。我个人是觉得虎八原车的235的胎宽已经比较均衡了,兼顾了省油和舒适,后续跑三年之后我考虑换一套235的普利司通静音轮胎,应该就比较妥当舒服了。
全文的分享到此为止,感谢大家的支持。
