Automobile tire screws may be affected by the following:

1. Insufficient fastening force: If the tire screws are not installed correctly or the fastening force is insufficient, the tire may loosen or fall off during driving, which will seriously affect the driving safety of the vehicle.

2. Thread damage: If the thread part of the tire screw is damaged or worn, it may lead to the screw not being screwed into the hub correctly or loosening, which will affect the fixing performance of the tire.

3. Corrosion and rust: If the tire screws are exposed to wet or corrosive environment for a long time, corrosion and rust may occur, which will reduce the strength and durability of the screws and affect their fixing effect.

4. Improper tire replacement: When replacing tires, if the tire screws are installed incorrectly or improper tools are used, the screws may be damaged or deformed, which may affect their fixing effect.

5. Too tight or too loose tire: Too tight or too loose tire screws will have adverse effects on the tire. Too tight may lead to tire deformation or damage, while too loose may lead to tire loosening or falling off.

To sum up, the influence of the above factors on the automobile tire screws may cause the tire to be loosely fixed, fall off or be damaged, thus affecting the driving safety and stability of the vehicle. Therefore, it is an important measure to regularly check and maintain the installation state and fastening force of tire screws to ensure the safety of vehicles.
