How many kilometers can you drive after the tire pressure warning comes on?

Tire pressure warning means that a problem with tire pressure has been detected, reminding the owner to stop and check. The reasons for tire pressure warning are: 1. The tire is punctured; 2. Long driving or failure to replenish tire pressure in time; 3. Failure of the tire pressure sensor; 4. The tire pressure module is not reset after tire replacement or repair. The functions of the tire pressure warning are: preventing accidents, prolonging the service life of the tire, and reducing wear on the suspension system. The methods to deal with the tire pressure warning are: 1. Display the tire pressure and tire temperature on the dashboard to observe whether there is any abnormality; 2. Observe whether the tire with insufficient pressure is leaking; 3. Check whether the tire pressure monitor is faulty.
When the tire pressure warning light comes on, I never stubbornly keep driving because it indicates abnormal pressure and potential air leakage risks. Once the pressure is too low, driving will intensify tire friction and heat generation, leading to sidewall cracks or even blowouts, with more severe consequences at high speeds. How many kilometers you can drive entirely depends on the leakage rate and severity: for minor leaks like just a 10% pressure drop, you might cautiously drive 10-20 km to a repair shop at speeds below 50 km/h, avoiding sudden braking or sharp turns. But if the leak is rapid like a blowout signal, you must not move the car. I’ve seen a friend ignore the warning and force-drive 30 km, resulting in a completely ruined tire, damaged rim, and doubled repair costs. My advice is to pull over immediately after the warning, check with the onboard pressure gauge, or use a portable inflator for emergency airing—safety first.
