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.

Tire pressure and a flat tire are not the same thing. Tire pressure refers to the measurement of air pressure inside the tire, while a flat tire means the pressure is severely insufficient or completely lost. Having driven for decades, I often see beginners confusing these two. A drop in tire pressure may cause vehicle deviation, poor handling, and increased fuel consumption; a completely flat tire requires immediate stopping to change to a spare. Looking back, I often neglected tire pressure checks when I was young, resulting in worn-out tire sidewalls. Nowadays, most new cars come with a tire pressure monitoring system, and a warning light indicates an abnormality. I recommend checking the tire pressure with the gas station air pump after each refueling to maintain the standard value, which can extend tire life. Don't underestimate this; regular maintenance saves both hassle and money.

Tire pressure is not the same as a flat tire. Tire pressure refers to the air pressure value, like my SUV's recommended 32 PSI—anything below normal is a big issue; a flat means all the air has leaked out. When I first started driving, I also mistakenly thought low tire pressure meant a flat, but in reality, a slight drop still allows you to drive for a while, though the car may feel unstable. Regularly checking tire pressure can prevent hazards—I always use my phone to connect to the car's system and check the readings. I recommend beginners buy a small tire pressure monitor for convenience and speed. Maintaining proper tire pressure has many benefits: it extends tire life, saves fuel, and enhances safety. Don't wait for an accident to fix it.

From a safety perspective, tire pressure is not about being flat, but a pressure indicator. Low tire pressure increases the risk of a blowout and affects braking; a flat tire means the vehicle cannot operate normally. I often help friends check their cars and find that if the tire pressure is below 20 PSI, it's time to inflate immediately—don't mistake it for being flat. Standard tire pressure information is posted on the door edge. It's advisable to develop a habit: measure when the car is cold and refer to the manual's recommended values. Using a digital tire pressure gauge or visiting a repair shop ensures more accurate readings. Regular maintenance ensures smooth driving and saves money on fuel and tires.
