Spare tire thousand days to use in a moment hand-in-hand to teach you to change tires

Tires are like human shoes for cars, and it will be difficult to walk without shoes. Then someone asked, the electric teacher

"When humans were not fully evolved, they lived well in shoes?" "You, get out, can you still have a good lesson?" Can modern society be compared with ancient times, and which of today's human beings will catch a sheep and eat it raw when they are hungry? Please listen carefully to the students who have just asked the question and pull them out and bury them. ”

Below we continue to lecture, tires belong to the wear and tear supplies, just as the brake pads will wear out over time, in general, the harder the tires are more wear-resistant, the replacement cycle is longer, the original tires of ordinary family cars are slightly hard, the tire factory is for your cost considerations, save you old money, basically the tires of general household cars, on the basis of not being hurt by the outside world, driving 4-50,000 kilometers is still very common.

So under what circumstances it is time to change the tire, which can be divided into the following points:

1. It is recommended to observe the tire once a month, mainly the pattern part of the tread, when you see, the tread shoulder and the tread grain have some slag off, when the slag is dropped with a slight buckle with the hand, it means that the tire is aging, at this time it needs to be changed, often inventory cars and long-term parked cars, easy to appear, this situation is less than the number of kilometers and no grinding to the limit mark also have to be changed.

2． Tires with excessive wear of the tread, the grip will be greatly reduced, if you walk every day when the basement turns, suddenly from one day, the tires have some squeaks, you exclude the basement to re-lay cement and other factors, often your tire grip drops, the same speed turns the corner of the basement, the tire lateral grip decreases, and there is a squeaking sound caused by some slight sliding, at this time you need to observe the tire.

3． The reason is similar to the previous article, when you drive on the road, it is generally obvious on rainy days, before the normal braking force, suddenly in the same rainy day and the same force, now there is a click of ABS intervention to release the brake maneuver, which clearly indicates that the tire grip is declining, and the tire needs to be carefully checked.

4.Zui after a point is simple, observe whether the surface of the tire appears damaged, bubbling and other phenomena, you do not want to install such a tire such as a bomb at the same time to risk your life on the road, right? In addition, if you are stuck by an object such as a nail and do not hurt the sidewall of the tire, you can continue to use it after repairing the tire. If the tire sidewall is punctured and the tire needs to be replaced, because the tire sidewall will be crushed and deformed every time it is rolled, the inner film may fall off due to repeated rolling, and it is dangerous if it is not detected.

Puncture

If there is a puncture or air leakage while driving, it is necessary to replace the spare tire, and you don't want to spend a lot of money to ask the rescue car to be dragged to the repair shop, right? The rest of the towing fee is better than calling two or three friends to a small barbecue! So in order to save you money, let's explain how to replace the spare tire correctly.

Tire Change Tutorial:

1. First of all, setting up the triangle warning sign at 50-150 meters is an essential step, you don't want to rear-end the car in the tire replacement process, right?

2. Open the trunk to remove the tire changing tool and spare tire. The vehicle in the picture is the spare tire position of the SUV model is also relatively rarely placed under the chassis, and the spare tire of the general model is placed under the trunk mat.

The spare tire is under the chassis

Use the on-board tool to loosen the knob that holds the spare tire

Until the spare tire falls

3. Therefore, the tire replacement step is also one step more than the general model, and the iron chain of the suspension spare tire is twisted with the vehicle tool until the spare tire lands.

4. Next, when using a wrench to loosen the tire and tighten the screw, it is necessary to use a diagonal way to twist, which is mainly to prevent the nut from deforming due to uneven acceptance, remember not to screw it all down. In general, the screws on the wheels are very tight, so when the screws are opened, you can use the foot to step on the wrench, and it is much easier to change hands after loosening.

When placing the jack, do not align the card slot on the measurement to avoid damage to the body

5. Align the jack and slowly raise it.

6. When the vehicle is fully supported, then unscrew all the bolts on the wheels and place them in a position that is convenient for their own memory to prevent loss.

Fix the bolt by hand first

Then tighten it with a wrench

7. Then change to the spare tire, use the wrench to screw until it can not be moved, here also in accordance with the diagonal way to operate, zui also use the foot to tighten the screw again.

After the final spare tire installation is completed, you need to remember that the spare tire specifications are different from normal tires, replace the full-size tires as soon as possible, and do not use them for a long time. In addition, the speed specified by the spare tire is strictly followed, and the high speed limit of the zui marked on the spare tire should not be exceeded to avoid danger.

Changing tires is an essential self-help skill in the car career, so as not to wait helplessly for rescue after an accident. Of course, it is important to save you money on a barbecue. After zui, I sincerely wish everyone that this skill will never be used in the middle of the future use of the car.
