What Are the Causes of Insufficient Tire Pressure in Cars?
3 Answers
The causes of insufficient tire pressure in cars are: 1. Inadequate inflation during tire replacement; 2. Failure to regularly check tire pressure and make appropriate adjustments; 3. Punctures while driving, leading to air leakage and insufficient pressure. Hazards of low tire pressure: 1. Increased contact area between the tire and the ground, raising internal tire temperature during driving; 2. Severe deformation of the tire sidewall, accelerating aging of internal steel wires and fabric layers, leading to blowouts; 3. Increased fuel consumption and reduced tire lifespan. Factors affecting vehicle tire pressure: 1. Seasonal factors: Thermal expansion and contraction in summer and winter result in different tire pressures; 2. Load conditions: Tire pressure varies when empty, half-loaded, or fully loaded; 3. Tire condition: Worn tires and unworn tires have different pressure requirements.
I've encountered the issue of insufficient tire pressure quite a few times. The most common causes are nails or small stones puncturing the tire, leading to slow leaks, or aging and loose valve cores allowing air to gradually escape. When the weather turns cold, tire pressure drops quickly due to gas contraction, while high temperatures can cause uneven expansion. Older tires that have been in use for several years may develop cracks in the sidewalls, leading to seepage. Negligent driving habits, such as frequently driving over potholes or scraping against curbs, can accelerate tire wear. Infrequent checks are also problematic—many car owners, like I used to be, are too lazy to measure tire pressure for months, only to find it has unknowingly dropped. I recommend developing a habit of checking tire pressure monthly, using a tire gauge when the car is cold in the morning, and maintaining it near the manufacturer's recommended value. Don't wait for the warning light to come on while driving. This practice helps prevent the risk of blowouts, ensuring safety and convenience.
During long-distance driving, I felt the car was unstable and found out it was due to insufficient tire pressure. There are several main reasons: the tire was punctured by a sharp object, causing a slow leak; the rubber of the valve core deteriorated, leading to poor sealing; a sudden temperature drop increased air density and reduced tire pressure; aging tires leak faster. In summer, after parking in high temperatures, cold contraction may also result in insufficient pressure. Driving habits such as fast turns or sudden braking increase tire pressure and accelerate leaks. Neglecting regular checks is common—I didn’t pay attention until the dashboard alarm alerted me. Now, I always check the tire pressure when refueling to ensure it’s within the normal range. Maintaining proper tire pressure reduces fuel consumption and wear, ensures smoother driving, and provides peace of mind, especially at high speeds.
