How long can you typically drive with a flat tire?

You can typically drive for about an hour. Carefully inspect the tire for any abnormalities after getting out of the car. If you confirm there are no issues like nails puncturing the tire or air leakage, you can slowly drive the car to an auto repair shop for inspection. Relevant information about tire pressure is as follows: Introduction: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car—damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the car's performance and power. Hazards of overinflated tires: The friction and adhesion of the tire will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort.
That time I drove to the countryside, a small cut was made on my tire by a stone, causing a slow leak. After the system alerted me, I insisted on driving 15 kilometers to the repair shop for inspection, and the tire was almost worn flat. Generally speaking, how long you can drive after losing pressure depends on the speed of the leak: for slow leaks like small punctures, you might barely manage 20-30 kilometers; but for fast leaks like large cracks, the tire could go completely flat in just three to five minutes. Never push your luck—reduce your speed to below 40 km/h and find a safe place to stop. Continuing to drive is too risky; the tire heats up quickly, and the cord layers can easily tear, leading to a blowout or rim deformation, which could cost thousands to repair. I recommend always keeping a tire pressure gauge or a portable air pump in your car—prevention is key.
From a safety-first perspective, the driving time after tire pressure loss is very limited. In a slow leak scenario, if the pressure drops gradually, you might manage to drive slowly for 10-20 km to a service station. However, with rapid air loss, you may not even make it 1 km before needing to stop. The key is to monitor the situation while driving: if you feel steering wheel vibration or vehicle instability, immediately slow down and pull over. Otherwise, the tire may overheat, expand, and burst, leading to loss of control and accidents. I've experienced similar situations—pulling over to change to a spare tire resolved it. Keeping emergency tools in the car is a wise investment, and developing a habit of monthly tire pressure checks is essential. Remember, risking extra distance could lead to greater losses.
Tire air leakage can be divided into two types: slow leaks through small holes cause gradual pressure loss, potentially allowing driving for half an hour or up to 50km, but cumulative damage occurs; rapid leaks from large punctures flatten tires within minutes, requiring immediate stop for inspection. Driving with underinflated tires overloads sidewalls, potentially damaging internal materials or causing separation from rims. I recommend using TPMS (Tire Pressure Monitoring System) for early warnings - when alerted, slowly drive within 100 meters to pull over. Don't wait until problems escalate.
