Do not oil the tyre bolts and nuts
In wheel maintenance, a few owners of vehicles want to prevent bolts and nuts from rusting on wheels. When installing, they lubricate bolts and nuts with ingenuity, which is not only a mistake but also a hidden danger to traffic safety. When the bolts and nuts are tightened, they have the characteristics of self locking each other. After being coated with lubricating oil, the self locking coefficient between the two is smaller and the self locking performance decreases. The bolts and nuts are easy to loose and even fall off when the car is running at high speed, thus causing traffic accidents.
