The first method, the "spicy strip" tire repair method. When a car tire is punctured, the quickest and easiest way is to repair the tire with adhesive tape. Apply some glue directly to the tire hole, and then insert the adhesive tape directly into the hole with a tool, thus blocking the hole. It's just that the wound will be bigger and easier to leak again.
Second, cold repair or fire repair. These two methods of tire repair are similar. First, smooth the hole in the car, and then directly stick a piece of tire repair glue to fix it. This is a cold patch. Fire patching means adding a little sulfide in this process, and then this film will be "baked" and stuck to the inner wall of the tire, which is more secure than cold patching. It's just that the wall of household tires is thin, and poor technology may burn tires.
The third kind, mushroom nails. This tire patching material is like a thumbtack. When repairing a tire, grind the inner wall of the tire flat, then pass the small rubber strip in front through the pierced hole, then stick the film inside the tire firmly, and then remove the extra rubber strip outside. This method should be the safest and even the most expensive.
Then how many times can the tire be mended? This is related to the brand of the tire. A few can only be mended once, but most have to be mended four times. As for others without quality assurance standards, you can make up as many times as you want, but the more you make up, the more unsafe it is. And if the hole is too big or the tire sidewall is injured, it is better to change a new tire.
