Can You Still Drive with 196 kPa Tire Pressure?
2 Answers
Tire pressure of 196 kPa is not suitable for normal driving, and it is recommended to inflate the tires as soon as possible. Low tire pressure increases the contact area between the tire and the ground, leading to abnormal temperature rises inside the tire during driving. Additionally, severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, increasing the risk of a blowout. It also raises fuel consumption and reduces tire lifespan. The relationship between tire pressure and vehicle handling stability: Cornering stiffness is a crucial parameter determining vehicle handling stability. Tires should have high cornering stiffness to ensure good handling stability. Tire pressure significantly affects cornering stiffness—higher pressure increases stiffness, but beyond a certain point, stiffness no longer changes. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, 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.
Whenever I notice the tire pressure is slightly low, I always consider safety factors. 196 kPa is indeed a bit low. The recommended tire pressure for normal cars is usually between 210 to 250 kPa, which can be specifically referenced on the door frame label or user manual. For short trips, you might barely manage, but there are several risks. First, tire wear accelerates, especially during high-speed driving, potentially causing uneven wear and premature tire replacement. Second, fuel consumption increases because low tire pressure enhances ground friction. The most severe risk is the heightened chance of a tire blowout, particularly during long-distance or high-speed driving. I remember one time when I was negligent and drove for a while, I clearly felt the steering becoming unstable, and I had to spend extra time pulling over to check. I recommend carrying a tire pressure gauge with you. If you notice the pressure is low, find a gas station to inflate it to the standard value immediately—don’t delay, as driving safety comes first, especially when carrying passengers. Tire pressure tends to drop in cold weather, so developing a habit of regular checks is crucial.
