At what tire pressure should a car not be driven?

[Dale]

Tire pressure should not be lower than 1.2 bar. Hazards of over-inflated tires: Reduced friction and adhesion of the tire, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates localized wear of the tread center pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends 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 on the road, they can easily penetrate the tire, causing internal cracks or blowouts. Hazards of under-inflated tires: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; increases tire body deformation, making the sidewalls prone to cracking and causing flexing movements that lead to excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
