Can a Car Still Be Driven After Being Submerged in Water?

Whether a car can still be driven after being submerged in water depends on the water level and the extent of submersion. Related details are as follows: Definition of a Water-Damaged Car: If the water level does not reach the chassis, it is not considered a water-damaged car. If the water reaches the chassis, it is classified as a soaked car, which is the mildest form of water damage. If the water level is almost above the wheels, it is a half-submerged car, where water enters the cabin and wets the seat cushions and lower parts. If the water level is above the dashboard, it is a fully submerged car. In fully submerged cars, the water reaches the waistline of the vehicle, causing corrosion to the electronic circuits, engine compartment, and interior. Although such cars can be repaired and used, they pose significant risks. Major Risks of Water-Damaged Cars: Electronic system failures; engine failures; automatic transmission damage; moldy interiors; other affected areas include the air conditioning, audio system, and interior lighting, which are also heavily impacted by water submersion.

What Causes Bulges in Car Wheels?

Bulges in car wheels are caused by the breakage of the tire cord fabric layer in the sidewall, which allows the internal air to escape from the broken cords, resulting in the thin rubber supporting the bulge. The reasons for tire cord breakage are: 1. Wheel quality issues; 2. Impact to the wheel; 3. Insufficient tire pressure. A wheel consists of a rim and spokes. The rim is the component that mounts and supports the tire on the wheel, while the spokes are the supporting components between the axle and the rim. Tire maintenance methods include: 1. Regularly checking tire pressure; 2. Paying attention to tire wear indicators; 3. Noting the expiration date of tires; 4. Adhering to the schedule for four-wheel rotation.
