Is a tire pressure of 195 kPa normal?
1 Answers
A tire pressure of 195 kPa is not normal. Driving with a tire pressure of 195 kPa is not advisable. The normal range for tire pressure is 230 to 250 kPa. When driving with insufficient tire pressure, the most noticeable effect is increased fuel consumption. Low tire pressure increases the contact area between the tire and the road, leading to greater friction and added driving resistance, which in turn increases fuel consumption. Additionally, insufficient tire pressure accelerates tire wear and reduces the tire's lifespan. The relationship between tire pressure and vehicle handling stability: Cornering stiffness is a crucial parameter that determines a vehicle's handling stability. Tires should have high cornering stiffness to ensure good handling stability. Tire pressure significantly affects cornering stiffness—the higher the tire pressure, the greater the cornering stiffness. However, beyond a certain point, increasing the pressure does not further change the stiffness. Introduction to standard tire pressure: According to the international standard GBT2978-2008, the recommended tire pressures are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.
