Should I add air if the tire pressure is 210?

Tire pressure at 210 requires inflation, it is recommended to fill up to 250kpa. Tire pressure should not be too high or too low. If the tire pressure is too high, the contact area between the tire and the ground will decrease while driving, which will affect the car's grip and handling. If the tire pressure is too low, the tire may exhibit wave-like deformation during high-speed driving, increasing the risk of a blowout. Tires are the only part of the car that comes into contact with the ground and have a shelf life. Tires can be used for four years, so it is recommended to replace them every four years. After replacing the tires, it is essential to perform a dynamic balance again to prevent abnormal shaking of the wheels during high-speed driving.
I've driven several cars before, and I always refill the air when the tire pressure drops below 220 kPa. A reading of 210 is clearly too low, as the normal tire pressure range for most sedans is between 220 and 250 kPa. Long-term underinflation is particularly damaging to tires, causing significant wear on both sides—I once ruined a tire this way. It also increases fuel consumption by about 0.5 liters per 100 kilometers. Moreover, the car feels unstable when cornering, and emergency braking distances become longer, which is really unsafe. Pay extra attention before driving on highways in summer, as rising tire temperatures will further increase the pressure. Just go to a repair shop to refill the air and have them check for any slow leaks while you're at it.
