Is Tire Pressure the Same as a Flat Tire?
2 Answers
Low tire pressure does mean the tire is underinflated. Strictly speaking, tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is the heart of the car, and its damage can lead to the end of the car's life. Similarly, tire pressure is like the blood pressure of the car, and its level has a crucial impact on the vehicle's performance and power. Below is more related information: 1. The relationship between tire pressure and load capacity: Tire pressure is an indicator of a vehicle's load capacity. The load a car can carry depends on the level of tire pressure. According to the relationship between a tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity. For example, a tire with a load index of 80 has a load capacity of 300 kg at 0.15 MPa, but this increases to 450 kg at 0.25 MPa. This shows that tire pressure significantly affects a vehicle's load capacity. 2. The relationship between tire pressure and vehicle power: When a car is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance. Tire pressure greatly influences the rolling resistance coefficient. When pressure decreases, the rolling resistance coefficient increases rapidly because underinflated tires deform more during rolling, leading to increased hysteresis loss. Therefore, proper tire pressure ensures good vehicle power performance.
Tire pressure is not the same as a flat tire. Tire pressure refers to the air pressure inside the tire, measured in PSI or Bar. For example, passenger cars typically maintain a pressure between 30-35 PSI. A flat tire means the air has completely leaked out or the pressure is zero. Low tire pressure can be an early warning sign; if ignored, it may lead to a flat. As a new car owner, the first time I encountered this, I thought the tire was damaged, but the tire pressure gauge showed only 25 PSI. After inflating, it returned to normal. Long-term low tire pressure increases tire wear, raises fuel consumption, and even the risk of a blowout. Experts recommend checking tire pressure monthly, especially during seasonal changes when temperature fluctuations affect pressure. Buying a simple tire pressure gauge to check it yourself is sufficient—don’t wait until the tire goes flat to address it. Safety first.
