大家都知道，复杂的路况往往会为出行带来更多的困难，如果经常在非铺装路面行驶的话，轮胎的磨损一定是很多严重的，从而也就导致了轮胎容易出现爆胎的情况。轮胎突然爆胎可能会直接造成交通事故，如果能够控制好的话，也是能够避免事故的。那么问题来了，如果轮胎需要替换，正确换胎的步骤你知道吗？下面
济南宝马汽车专修人员为您分析：
As we all know, complex road conditions often bring more difficulties to travel. If you frequently drive on unpaved roads, the wear and tear of the tires must be severe, which leads to the risk of tire blowout. A sudden tire blowout may directly cause a traffic accident, and if properly controlled, accidents can also be avoided. So the question is, if the tire needs to be replaced, do you know the correct steps for changing the tire? Below is an analysis by the BMW repair personnel in Jinan:
先支警示架
First support warning frame
很多车友一旦路上轮胎出现问题，都是先下车检查轮胎，然后立马就会着手换胎，殊不知，这样的操作方式可是大错特错的！尤其是在高速路上，这样的行为非常的危险！所以，轮胎被扎需要替换，步是先支警示架！
Many car enthusiasts, once there is a tire problem on the road, first get off the car to check the tire, and then immediately start changing the tire. Little do they know that this operation method is completely wrong! Especially on highways, such behavior is very dangerous! So, if the tire is punctured and needs to be replaced, the first step is to install a warning frame first!
正确的方法是：一旦轮胎被扎或者漏气，需要换胎，首先要拿出警示架，在车后不少于150米的距离，立起！建议，警示架好准备2个以上，这样再隔四五十米摆放一个，给后车足够的警示预警时间。这样的做法是先保证自身的安全，才能再去换胎！
The correct method is: once the tire is punctured or leaks and needs to be changed, first take out the warning frame and stand it up at a distance of no less than 150 meters behind the car! Suggest preparing two or more warning frames, so that one can be placed every forty to fifty meters to provide sufficient warning time for the following vehicles. This approach is to ensure one's own safety before switching tires!
再支千斤顶
Support the jack again
千斤顶的位置是非常重要的，既应该靠近更换的轮胎，又不能影响到正常的换胎，一般来说，应该在离车轮20cm左右处，也有一些车的车身侧面下端就有放置千斤顶的位置标识。
The position of the jack is very important, it should be close to the replaced tire and should not affect the normal tire change. Generally speaking, it should be placed about 20cm away from the wheel, and there are also some cars with a location mark for placing the jack at the lower end of the body side.
在固定好千斤顶的情况下，缓缓的车子顶起，切记速度一定要慢，过快的速度很有可能导致千斤顶滑落。升完千斤顶之后，可以将备胎放在车底边梁下面，以防止千斤顶突然失效。
With the jack fixed, slowly lift the car and remember to slow it down. Excessive speed may cause the jack to slip. After lifting the jack, the spare tire can be placed under the bottom edge beam of the car to prevent sudden failure of the jack.
拆卸已经损坏的轮胎
Dismantle damaged tires
车子的后备厢下方都会有原厂自带的扳手等工具，在拆卸轮胎的时候要使用随车工具中的套筒扳手，且谨记"向右是紧、向左是松"的规则，否则会有着适得其反的作用。如果没有，建议事先装备好，这东西平时用不着，关键时刻却特有用！
Under the trunk of the car, there will be factory equipped wrenches and other tools. When disassembling tires, it is necessary to use the socket wrench from the accompanying tools, and remember the rule of "tightening to the right and loosening to the left", otherwise it will have a counterproductive effect. If not, it is recommended to equip it in advance. This item is not usually needed, but it is particularly useful in critical moments!
拆卸轮胎的时候将轮毂上的螺丝扭松即可，但也是有一些小技巧的，用扳手的时候一定要以对角形式松螺丝，松完一个螺丝之后，下一个要松的就是和个螺丝对角的螺丝。这样做能够让轮胎被均匀的拆下，防止某个方向突然松掉而砸到人。
When disassembling the tire, just loosen the screws on the wheel hub, but there are also some tricks. When using a wrench, be sure to loosen the screws diagonally. After loosening one screw, the next one to loosen is the screw that is diagonally opposite the first screw. This can allow the tires to be evenly removed, preventing them from suddenly loosening in one direction and hitting people.
更换上完好无损的备胎
Replace with a spare tire that is intact and undamaged
将之前放在底边梁下的备胎拿出，同时将拆下来的轮胎放入底边梁下，这样做的原因同样是为了安全。轻轻的将轮胎提起，在螺丝孔对齐之后向里推就可以了，接下来需要将螺丝拧好，备胎的更换就完成了。
Take out the spare tire that was previously placed under the bottom edge beam, and at the same time, place the removed tire under the bottom edge beam for safety reasons. Gently lift the tire and push it inward after aligning the screw holes. Next, you need to tighten the screws to complete the replacement of the spare tire.
In addition, after replacing the tire, be sure to load the tire changing tool and the replaced tire into the car, and remember to take away the warning triangle! Also, prepare a built-in inflator pump on the car, as some spare tires may run out of gas after a long time, so be prepared!
