What are the safety hazards of a tire pressure of 2.2?
2 Answers
Under normal circumstances, a tire pressure of 2.2 poses no safety hazards and falls within the normal range. However, winter is an exception due to the thermal expansion and contraction of tires. A tire pressure of 2.2 is slightly low in winter. It's important to note that the commonly referred-to tire pressure is measured when the vehicle is cold. Tire pressure refers to the air pressure inside the tire, and its level plays a crucial role in the performance and power of the vehicle. The load capacity of the car depends on the tire pressure. Maintaining normal tire pressure is essential. Excessive tire pressure reduces the friction and adhesion of the tire, affecting braking performance, and can also cause steering wheel vibration and deviation, reducing driving comfort. Insufficient tire pressure increases the friction coefficient between the tire and the road surface, leading to higher fuel consumption, and can make the steering wheel heavy and prone to deviation, among other factors detrimental to driving safety.
I once drove for a long time with tire pressure at 2.2, and that time on the highway, I almost had an accident. Low tire pressure causes greater tire deformation, significantly weakens grip, and results in slower braking response, requiring a longer following distance to avoid rear-end collisions. It's even worse in the hot summer when internal tire temperatures rise easily, greatly increasing the risk of a blowout. Wear also becomes uneven, with the inner side wearing out faster, bringing tire replacement costs a year or two earlier. Fuel consumption can increase by about five percent, making every refueling painful. Checking weekly with a simple tire pressure gauge and making it a habit can prevent problems before they occur. Normal tire pressure is usually in the range of 2.3 to 2.5—anything lower carries many hidden dangers. Safety first, don’t take it lightly.
