Being supported by a jack for a long time, the direction can't be corrected for a while. Due to the geometric positioning of the suspension, the front wheel will always be subjected to additional external force, and the forces on both sides of the frame will be unbalanced. After a long time, the jack can easily change the frame, and the frame will be adversely affected.
So when changing the tire, don't let the old master keep dragging it. Change it as soon as possible. It's best not to send it for repair. People are watching. Secondly, when parking, try to make four tires on the same level, which is really not acceptable, and also make the tires on the same axis on the same line.
