Detailed introduction of the whole process of changing tires

With the advancement of science and technology, more and more high-tech applications are applied to automobiles. However, no matter how advanced the car is, it will eventually rely on tires to transmit power to the ground. The performance of the vehicle continues to improve. As the part of the vehicle that touches the ground, the working environment of tires can be described as very harsh. In addition to scratching accidents when we drive, the tires are probably the most problem-prone component. So today we will use pictures to explain the process of changing tires.

One *extreme situation is a puncture. We have discussed the issue of a puncture for a long time. The most important thing is not to panic when a puncture occurs. If the vehicle is parked in a place that will not affect the traffic as much as possible, the first thing to do after getting off the vehicle is to set up a warning triangle first.

At present, the spare tires of most cars on the market are installed under the floor of the trunk. Under normal circumstances, the vehicle-mounted tools are also placed here. You may ignore the spare tires. I remind you not to forget to check the condition of the spare tires and the vehicle with the vehicle regularly. Whether the tools are complete, so as not to lose the chain at the critical moment!

After taking out the spare tire and the tools that came with the car, first loosen the screws of the tire one by one, but do not completely unscrew it, but leave a few buckles at the back, and then use the jack to lift the car up.

It’s a sense of accomplishment to watch a one-ton car slowly rise in your hands, but don’t lift it too far. The wheels should just be off the ground, so that you don’t have to work hard to install the tires and cause trouble for yourself later. In addition, for safety reasons, don’t forget to tuck the spare tire under the car first after the car rises.

I think that installing the spare tire is the most troublesome problem in the whole process of changing the platform. Just letting the spare tire be honest with the axle is already a headache, so I just said that the jack should not be raised too high. Otherwise, you will be very tired at this time. It is very convenient if someone helps to hold the wheel, but if you are alone, it is best to adopt the posture like the picture below and put your feet against the tire.

One more thing to pay attention to when equipping the tires is not to tighten one screw in one breath, but to tighten them in a diagonal order. For example, the car we showed has four screws, we first screw the upper left corner screw, after a few tightening, change the lower right corner, and then the other two, the number of turns * is the same, so that all screws can be stressed Evenly.

After a few rounds of screwing, you can remove the jack when you feel that the power of your hand is basically unable to screw it. Just like when you start to remove the tire, you must tighten all the screws by the weight of your body, and also follow the diagonal The order of the lines.

After confirming that all the screws are tightened, the spare tire will be replaced…

Generally speaking, changing tires is really a small effort. Of course, it also requires certain skills. Everyone who drives frequently and loves driving should practice the process of changing tires. I believe many friends who have been driving for several years You may not have to change the tires yourself. If you have the opportunity to familiarize yourself with the process, you will be able to stay calm and confident in the event of an accident such as a puncture. In addition, I would like to remind everyone, don’t forget to check the tire pressure of the spare tire every time you do maintenance on the vehicle, and don’t wait until you find that the tire pressure is insufficient when you use the spare tire, it will be more troublesome…
