There are three repair methods for vacuum tires of battery cars: cold repair, hot repair and mushroom nail. Because the materials of each method are different, the price is also different. Electric vehicles need 25-50 yuan for cold patching, 35-70 for hot patching, and mushroom nails are the most expensive, 60- 100 yuan. The charges in different regions will be different, and the specific price still needs to be determined.

Mushroom nails are suitable for nailing large aperture gaps, which are generally used less, and are often used in automobile tires. The method is to disassemble the tire, pull out the nail, clean around the inner nail, and infiltrate a rubber strip sulfide with a fungus-like appearance from the inside to the outside of the tire to completely fill the wound. Then cut off the exposed part and coat it with special glue.
