What is the solution for a tire that always has low pressure?

When a car has a tire that consistently shows low pressure, it indicates a slow leak in that tire. In such cases, it is essential to promptly inspect and repair the tire to prevent potential safety hazards while driving. The functions of a tire are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. To mitigate and absorb vibrations and impacts during driving, preventing excessive vibration and premature damage to car components; 4. To adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring safety, handling stability, comfort, and fuel efficiency.
I've been driving for over 20 years, and the solution to a tire that always loses air pressure is actually quite simple. First, check the tire surface for any nails or glass shards that might have punctured it; this is the most common cause. If found, you can either repair it yourself with a tire repair kit or take it to a professional shop. If the tire looks fine, spray soapy water on the valve stem to see if bubbles form, indicating a leak; if it leaks, replacing the valve stem costs just a few dollars. Another possible issue is poor sealing at the wheel rim edge, such as rust or cracks, which may require sanding or having a mechanic adjust the sealing ring. I recommend using a tire pressure gauge weekly to ensure the pressure is within the range recommended in your vehicle's manual, typically 30-35 psi for most cars. Neglecting this can lead to faster tire wear, increased fuel consumption, and even a higher risk of blowouts at high speeds—don’t cut corners or delay. Finally, keep a portable air pump in your car for emergencies; it’s both convenient and safe. Developing this habit can save you a lot of trouble.
