What is the reason for insufficient tire pressure?
4 Answers
The reasons for insufficient tire pressure are: 1. Leaking valve stem; 2. Reduced tire sealing performance; 3. Vehicle carrying overweight items for a long time; 4. Uneven tire force distribution. The solutions for insufficient tire pressure are: 1. Check the cause of tire leakage and repair or replace the tire; 2. Replace the wheel hub and change driving habits to distribute force evenly on tires. The effects of insufficient tire pressure are: 1. Increased friction coefficient with the road surface; 2. Heavy steering wheel and tendency to deviate from course; 3. Increased movement in various parts of the tire; 4. Reduced functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim.
Insufficient tire pressure is a very common issue. I've encountered it several times over my decade-plus of driving. There are numerous reasons for low pressure, such as a small puncture from a nail causing a slow leak, gas contraction due to colder weather reducing pressure, or even a loose valve cap letting air escape. When checking, simply use a portable pressure gauge to measure it, and if the reading is low, inflate immediately. I've found that irregular checks can be quite dangerous, affecting vehicle handling and making turns unstable, while also increasing fuel consumption. Personally, I make it a habit to check every two weeks, ensuring the pressure stays within the standard range—this saves fuel and enhances safety.
Insufficient tire pressure is no trivial matter, and as a parent, I take this issue very seriously. It increases the risk of tire blowouts, especially during high-speed driving, and leads to longer braking distances, making accidents more likely. The most common causes are aging or damaged tires leaking air, as well as sudden drops in temperature during winter reducing pressure. For prevention, check the tire pressure every time you refuel—don’t wait for the warning light to come on. In terms of impact, it raises fuel consumption, accelerates tire wear, and shortens tire lifespan. Safety comes first, so I urge everyone to develop this habit.
I've encountered numerous cases while repairing tires. Insufficient pressure often stems from details like damaged valves, rusted wheel rim edges, or slow leaks. Using diagnostic tools to locate leaks—such as applying soapy water to check for bubbles—helps identify and fix issues quickly. Always refer to the standard pressure values on the door sticker and don't overlook them. Regular checks can prevent major repairs, keeping maintenance costs low and operations simple.
