Will the Tire Pressure of New Car Tires Gradually Decrease?
2 Answers
New car tire pressure will gradually decrease. If the car is left unused for too long, the tire pressure will drop. In fact, the tire pressure when the car leaves the factory is closer to the upper limit of the safe range, but as the car sits unused for longer periods, the tire pressure will change. Some manufacturers intentionally lower the tire pressure to prevent excessively high speeds. Since new cars require an adaptation period, during this time, to prevent high speeds that could lead to traffic hazards, the tire pressure is slightly reduced. Tire damage: If there is an issue with the tires when leaving the factory or if the tires are punctured during use, when the low tire pressure alarm for new car tires is triggered, carefully check whether the tires are damaged. Hazards of low tire pressure: Increased fuel consumption: Low tire pressure increases the contact area between the tires and the ground, thereby increasing tire friction, which leads to greater driving resistance and naturally higher fuel consumption. Shortened tire lifespan: Similarly, due to the larger contact area with the ground, tire wear is accelerated, reducing the tire's service life. Increased risk of blowouts: The increased friction causes the tire temperature to rise, making the tires softer and reducing their strength. When the tires are insufficient to support the vehicle's load, especially during high-speed driving, blowouts are more likely to occur.
As a new car owner who has been driving for a few months, I indeed noticed that the tire pressure gradually decreases over time. Initially, I didn't pay much attention, but later I felt the ride becoming bumpy. Upon checking, I found the tire pressure had dropped significantly from the factory setting. This is mainly because the rubber material of tires naturally allows air to permeate, and air loss through the tire walls is normal, especially noticeable on days with significant temperature fluctuations. I've developed a habit: using a digital tire pressure gauge to check all four tires every two weeks, and topping them up if the pressure is low. New cars usually come with higher tire pressure settings, but it will gradually decrease. If not addressed regularly, tires will wear out faster, fuel consumption will increase, and safety risks will rise. I recommend keeping a portable air pump in the trunk for convenience, so you don't have to wait until the tires deform to take action. These small daily maintenance tasks can make driving much more reassuring.
