Notes on repairing tires

I went to the 4S point to inspect the car in the morning and was told that a nail had been stuck in the left rear tire and the air was slowly leaking. So after returning home for lunch, he took a short break and went to a nearby auto repair shop to repair the tires. The store owner saw it and said it was easy to handle. I asked how to make up? Do you want to make mushroom nails? The store owner said that there was no need, so he could just make a supplementary meal. How much is it? Answer 30 yuan.
The first step is to remove the tire. The little guy first pushed under the pedal, but I stopped him; then he pushed the “beam” and lifted the rear tire without leaving the ground; so under my guidance, he pushed under the rear wheel horizontal axis (the working position of the jack marked in the user manual). When separating the tire from the hub, the metal surface of the shop’s machine had no protective layer. I asked them to come carefully, but I still scratched a little on the hub. I quickly stopped, but the boss said it was the only way. Do you want to continue? I said I couldn’t scratch the wheel hub, but the boss said that there was no way to peel off the tire. I said no more, restore it.
So I called my buddy who owned an auto repair shop and asked if I could win at the moment. I wanted to repair the tires. Brother said come and arrange it immediately. I know that not all employees in his factory have returned to work recently. There are so many people who come to maintain and repair cars, and the master is too busy to handle it.
After driving nearly ten kilometers, I arrived at my brother’s auto repair shop. Wow, business is good with more cars. My buddy personally repaired my tires. I asked you if it was okay? He said that I have been doing auto repair for more than 20 years, and repairing tires is still a piece of cake? So I acted as a helper and chatted while repairing the tires. He made a mushroom nail, but he doesn’t collect money. He’s the boss. But I didn’t do it. One code was one code, so the beautiful receptionist tried to smooth things over and said she would charge me a discount. She charged me 80 yuan. PS: Brother used two mushroom nails.

First, I repaired the tires at this auto repair shop. The Crown car hit a tree? The water tank should have been damaged.

Dude, the tire picking machine at the auto repair shop. The metal surface has a hard plastic guard plate that will not scratch the wheel hub.

After removing the nail, drill a larger hole to make mushroom nails.

V97 tire pressure monitor. When an alarm is turned on the instrument panel, it only means that one of the four tires is depressed, but I don’t know which tire is low, so the driver needs to test it one by one.

After drilling, polish the inside of the tire and apply glue.

Insert the mushroom spike into the tread from the inside.

The mushroom nail core is a steel core. Clamp it with wire pliers and pull it out hard.

Holy shit, it broke. It seems that this steel core is not very good either. Brother said the main reason is that the small hole drill is a little smaller.

The buddy used a drill to make the small hole bigger a little. This time, he successfully pulled the mushroom surface to fit the inner glue surface, and then rolled it with a special roller to tighten it, and cut off the pole with the tread. OK.

This is my V97.
