Will a Flat Tire Overnight Damage the Tire?
2 Answers
Leaving a tire flat overnight can cause damage. Here is the relevant information: 1. Reason: A flat tire left overnight may damage the tire's cord layer. Since the tire bears the entire weight of the car, leaving it flat overnight can cause deformation, even if no obvious issues are visible, which shortens the tire's lifespan. 2. Tire Pressure: Most modern car tires are tubeless and are considered low-pressure tires. The normal tire pressure range for general household cars is typically between 2.2 bar and 2.6 bar. If the tire pressure is within the normal range during inspection, a slightly flat appearance is normal.
As someone who has long been concerned about automotive safety, I believe that leaving a flat tire overnight can indeed cause damage. If the tire is completely flat, the entire weight of the vehicle rests on the weak sidewalls, and over time, the rubber can deform or develop cracks—just like how prolonged bending under heavy loads can strain your back. This is especially true when temperature fluctuations are significant, such as hot summer nights or cold winter nights, as the rubber is more prone to fatigue and cracking. This increases the risk of a blowout while driving and compromises handling safety. I recommend that if you discover a flat tire, don’t delay—immediately replace it with a spare or use an onboard air pump to check for leaks. For prevention, use a simple tire pressure gauge to check the pressure monthly, keeping it near the recommended value. Developing this habit can save you both hassle and money. Remember, safety is no small matter—acting promptly is the most reliable approach.
