How long can you drive with tire pressure below 200?

A tire pressure of 200 is too low, and driving long distances under such conditions can harm the tires. It's best to adjust to the normal tire pressure before driving. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends and deforms the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, leading to internal cracks, blowouts, and potential tire bursts. Hazards of insufficient tire pressure: Increases friction with the road surface, raising fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement in various parts of the tire, leading to abnormal overheating due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, resulting in damage and abnormal wear; Multiplies friction between the tire and the ground, sharply increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire bursts; Increases tire deformation, making the sidewalls prone to cracks and generating excessive heat due to flexing, accelerating rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and speeding up shoulder wear.
I remember one time when my tire pressure dropped to around 190, I was still able to drive a short distance to the repair shop, covering just a kilometer or two, keeping my speed below 30 km/h. However, it was quite risky as the tire could easily deform and overheat, leading to a blowout, especially at high speeds. I suggest not taking the risk of driving for too long and finding a place to inflate the tires immediately. A portable tire inflator is a great helper to keep in the car for emergencies. Regularly check the tire pressure, using a tire pressure gauge monthly to maintain the recommended value, which can help avoid similar issues. By the way, low tire pressure also increases fuel consumption. I experienced a 20% rise in fuel costs after just a few days of driving, so timely action is the best strategy.
Speaking of tire pressure below 200, I must remind myself that driving in this condition for too long is absolutely unacceptable. The recommended tire pressure is usually above 220, and anything lower indicates danger. Once I had a tire pressure of 180 and drove to a gas station just three kilometers away, but I drove slowly and carefully the entire way. The acceptable duration depends on the distance and environment—short distances at low speeds might be barely manageable, but long distances or bumpy roads can easily lead to a blowout. I would recommend stopping immediately to address the issue, calling for roadside assistance, or finding the nearest repair shop. A tire pressure monitoring system is extremely helpful; I installed one, and it automatically alerts me when the pressure is low. Make it a habit to check every two weeks—safety first, don’t gamble with your life.
