Methods to determine if a car tire is flat include: 1. One side of the vehicle is noticeably lower than the other three sides; 2. The steering wheel suddenly becomes heavier while driving; 3. The vehicle struggles to maintain a straight line while driving, exhibiting slight wobbling. The hazards of low tire pressure are: 1. Reduced tire lifespan; 2. Increased tire wear; 3. Low tire pressure can lead to elevated tire temperature after driving, increasing the risk of a blowout, and the tire sidewalls are prone to deformation while driving; 4. Decreased tire traction while driving, resulting in abnormal bumpiness. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to enable vehicle operation; 2. Supporting the vehicle load; 3. Mitigating and absorbing vibrations and impacts during driving, preventing severe vibrations from damaging car components.

I usually pay attention to whether the tires look sunken when driving, because if they're flat, the edges of the tires will be closer to the ground, making the entire wheel appear flatter. The difference is also noticeable while driving—the steering wheel suddenly feels heavier, or the car pulls to one side, especially at high speeds where the body may wobble unsteadily. Once during winter, my tire had a slow leak, and I didn’t notice it at first. As a result, my fuel consumption increased. Later, I bought a tire pressure gauge and found the pressure was too low, realizing that even a small leak could lead to big problems. Now, I’ve made it a habit to walk around the car after parking, checking the condition of all the tires. I also kick them lightly to listen to the sound—firm tires indicate proper inflation. Regularly checking tire pressure is crucial; I recommend doing it at least once a month to avoid driving hazards.

I've gotten used to using tools to check tire pressure now. My car is equipped with an electronic tire pressure monitoring system that displays real-time pressure values and automatically alerts when it falls below the recommended level. Without tools, I can crouch down and press the sidewall of the tire with my hand - if it gives way easily, it indicates insufficient air. While driving, if I hear a hissing sound of air leakage or notice increased steering wheel vibration, I need to check immediately. In summer, hot temperatures can cause tire pressure to rise, while in winter, cold weather may cause it to drop, so I make sure to measure it once more during seasonal transitions. The spare tire shouldn't be overlooked either, as it may lose air after prolonged storage. Before every long trip, I check it to ensure safe travels.

As a family car owner, I'm always concerned about tire leaks affecting safety, especially when driving with children. The basic method is to observe the tire's appearance: a normal tire has plump sidewalls, while a flat one appears wrinkled and sticks to the ground. While driving, if you feel the car shaking or pulling to one side, it might also indicate low tire pressure. I remember one time in the rain when my tire had a slow leak, the braking distance increased, and I almost had an accident. So now I make it a habit to check my tires once a week when I get out of the car, using a simple tire pressure gauge to maintain the standard pressure. Tires are more prone to leaks with significant temperature changes, so in the summer heat, it's important to watch out for blowouts. Developing this habit helps prevent potential hazards.
