Leaving a car with a flat tire overnight will not cause any harm. As long as the vehicle is not moved, a flat tire will not damage the wheel rims. Regarding the suspension, every car's suspension can handle a certain level of height difference, and the thickness of the tire ensures that the suspension won't be affected. The car door also won't deform, but it's best to call a professional tire service to help replace the tire and inspect it. More relevant information is as follows: 1. Emergency handling of a punctured tire: If a car tire is punctured and loses air, first determine the tire pressure, roughly how much it is. Is it completely flat, or just slowly leaking air? The car's built-in electronic devices can directly measure the tire pressure. Actually, the simplest method is to step on it with your foot to check. If there's some air left, it means you can still drive a short distance to reach a repair shop. Be careful not to drive too fast—keep the speed below 60 km/h, and avoid sudden braking. It's best to drive along the far right side of the road and slowly proceed to the repair shop. Repair shops have professional equipment and technicians. 2. Temporarily replacing with a spare tire: If stepping on the tire shows no reaction and it remains completely flat, and the situation is severe, then you should not continue driving. You need to replace it with the spare tire. Under the car's trunk, there are tools, including a jack and the necessary wrench for removing bolts. The location of the spare tire varies by car but is usually easy to find, typically under the trunk or in a conspicuous spot. When removing the bolts, because they were previously tightened with professional equipment, they might be very tight. If the wrench doesn't work, you can use your foot to kick it. Remember, the spare tire is only for temporary use and should not be used for an extended period. After replacing the tire with the spare, go to a repair shop as soon as possible to get a new tire.
