At what tire pressure level should a car not be driven?

[Laura]

Tire pressure below 1.0bar makes driving unsafe. Here is more information about tire pressure: 1. Modern vehicles come equipped with tire pressure monitoring systems that typically trigger an alert when pressure falls below 1.5bar. 2. For vehicles without TPMS sensors, it's recommended not to go below this threshold. The most severe consequence of underinflation is tire blowout, which poses significant risks. Below are the hazards of low tire pressure: 1. Increased friction coefficient during tire rotation causes abnormal deformation where the tread contacts the road. This creates irregular circular motion, elevating tire temperature. 2. While overinflation can also cause blowouts, underinflation often goes unnoticed. Prolonged driving with insufficient pressure severely damages tires and may endanger occupants. 3. Underinflation enlarges tire deformation, causing sidewall cracks and excessive flexing. This generates overheating, accelerates rubber degradation, fatigues the cord fabric, and breaks reinforcement cords. It also expands the contact patch, accelerating shoulder wear and increasing blowout risks. 4. Low pressure additionally increases fuel consumption, makes steering heavier, causes alignment issues. While perfect pressure maintenance is challenging, slightly higher pressure is preferable to dangerously low levels.
