What is the minimum tire pressure below which driving is not recommended?

[WestonDella]

The tire pressure monitoring system will issue an alert when the pressure falls below 1.5 bar, so this value is also a general recommendation for tires without pressure sensors not to go below this level. The normal tire pressure for most passenger cars typically ranges between 2.1 and 2.8 bar. Driving with excessively low tire pressure can cause the tires to overheat, soften, and potentially lead to a blowout. Tire pressure also varies with the seasons. In winter, it's advisable to slightly increase the pressure by about 0.2 bar above the standard tire pressure for your vehicle. In summer, when parking outdoors, the pressure can generally be about 0.1 bar lower than the standard to prevent blowouts due to high temperatures. For new tires, the pressure can be set about 0.2 bar higher than the standard, while for older tires, it's appropriate to slightly lower the pressure according to the standard.
