It is understood that now,tireIt is very common to be pierced by foreign objects, especially iron nails. Since there are not many places where tires can be repaired, once a tire is punctured and leaked, most car owners can only change the tire first, and then find a small repair shop on the roadside to repair it. Due to the low cost of repairing tires and it is difficult to make money, most of the general tire repair shops only provide simple external repairs, which are completed by using adhesive strips and strong glue to drill into the holes. The cost of a repair is about 10 yuan.
Auto repair experts said that this method of patching small holes in the tires is only used for temporary emergency relief and is a method that is gradually being eliminated. Because the strength of the external repair is often different from the original tire, the tire will be inconsistent in force after repair, and the tire skeleton is easily deformed. Moreover, this external repair method has a low degree of sealing, and air and water can easily enter the tire, resulting in steel in the tire. The line is rusty, and there are still hidden safety hazards when driving at high speed. Some tires are scrapped after only three or four months after external repair.

The pebbles in the tire tracks should also be cleaned up in time to prevent these potential hazards from causing tire air leaks.
