Why does the tire pressure monitor show 1.6bar and keep beeping?

If a CRV suddenly prompts to check tire pressure, it means the tire pressure data of the vehicle is insufficient. It is necessary to inspect the tires to determine the causes of the low pressure and then perform repairs to resolve the issue. Only then can the vehicle be used normally; otherwise, it may affect driving safety. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the central tread pattern, shortening tire lifespan; Increases vehicle body vibration, indirectly affecting the lifespan of other components; Excessive stretching deformation of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreased 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 underinflated tires: Increases friction coefficient with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire parts, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, resulting in bead damage and abnormal wear; Multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to blowouts; Increases tire deformation, leading to sidewall cracks and excessive heat from flexing, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.
A few days ago while driving, I also encountered the tire pressure display showing 1.6bar followed by continuous alarm beeping, which was really a headache. Upon getting out of the car, I noticed the left front tire was visibly flat—it turned out a small nail had punctured it, causing a slow leak. The tire pressure monitoring system is designed this way; it alerts you to inflate when the pressure drops below a safe threshold, such as 1.8bar. In summer, the hot weather causes air to expand easily, making the alarm more sensitive to even slight air loss. Now, I always keep an air pump in my car. Whenever the alarm sounds, I stop immediately to manually check, confirm which tire is leaking, and then carefully drive to a repair shop to fix the tire. Learning some basic maintenance beforehand saves a lot of hassle in daily life.
