In the first step, we need to prepare the tools and equipment needed in the process of disassembling the tires of the whole car, including a tire wrench and a small hook, both of which can be found in the trunk of the car, and a jack.
Step 2: Remove the tire nut and take out the small hook. As shown in the figure, hook the hole of the nut with a small hook, then pull it out and take off the white. There are five of them. Just remove du one by one.
By the way, the tire is stuck in a nail.
First, find out where there are nails and where the tire leaks. Draw with marks. Don't draw the mark too big, because some small nails are not easy to find. If there are no nails, it is really hard to find. If you can't find them, make a mark with those sharp objects (sharp sticks, sharp sticks, sharp pens) with wires and sharp points (remember never to let the wires fall out). Be sure to wait until the air is exhausted, otherwise the tires such as Goodyear and Pirelli will easily bulge, and then the tire pressure (valve) will be aimed at the left side of the pried tire. After prying, apply a little more lubricant to the prying tire to prevent it from eating the tire (cutting off the tire). Relatively speaking, it is relatively simple for the machine to go directly, but some tires are easy to get stuck when they are old. It is easier for the machine to walk slowly (remember to walk slowly and carefully), and then take it down to see if there are any conspicuous nails on the inner wall of the tire. If there is, there is no need to mark it. If not, stick a sharp object or wire into it to make a mark, or screw a cross screw into it and draw a box around the screw with a marker. Don't draw it too big, because if it is too big, the tire grinder will grind the wrong place and start grinding the inner wall of the tire. Spray asphalt cleaning agent after grinding, then scrape it with the one that scraped the tire, and carefully slide the ground powder down by hand. Don't let him stick to the freshly ground gap, or the film won't fill the hole. After sticking the film, roll it up and down a few times with a pulley, then knock it with a sledgehammer a few times, and then pour out the powder inside, and you can install the tire. When installing, it is best to shake the lubricating oil brush a few times before applying it to the upper side of the tire. When installing, take a picture by hand in the first step (to the upper right position). Step 2, pry open the back of the right lower tire pressure (valve) with a crowbar. If the tire falls directly above the machine, pry it up with another crowbar (insert it into the gap). Otherwise, if the tire edge gets stuck in the gap between the tire and the machine, the tire will be cut off 100%, and then the tire will be inflated after installation to see if there is any air leakage at the repaired place. Finally, tires must be installed. When installing the tire, the first screw must be screwed in place but not tightened, and it can only be tightened after tightening a diagonal line. The screws must be tightened diagonally, so as not to easily lead to the hub and brake disc not hanging in place. But it leads to the phenomenon that the screw is not tight enough (this situation is easy to break the screw). If the screw is tightened, the flow direction of the five-pointed star will be tightened. If all four tires are removed, finally tighten the screws, take a wrench (cross) and remove all four tire screws to ensure that all screws are fixed.
I hope the above suggestions can be adopted. Thank you.
