Does the absence of a car valve cap have any impact?

Car valve cap missing will have the following effects: 1. Nearly 60% of car tires lose their valve caps, leading to slow air leakage, which in turn causes uneven tire wear and insufficient tire pressure, both reducing the tire's service life. 2. Cars with treads that are too smooth or thin may skid or drift while driving; if the tire sidewall has cuts, scratches, or cracks, it is prone to blowouts causing accidents, and bulges caused by broken tire cords are even more severe. 3. Dust can seep in, affecting tire maintenance and care. If lost, it is recommended to install a new valve cap as soon as possible.
As a veteran auto mechanic with over 20 years of driving experience, I've seen countless minor issues. A missing valve cap may seem trivial, but it actually has significant consequences. Its primary function is to protect the valve core from dust, rainwater, or dirt. Without this protection, dust can clog the valve core, causing slow leaks. Over time, unstable tire pressure affects braking distance and handling, increasing the risk of skidding at high speeds. Worse still, during rainy seasons or humid weather, moisture can corrode the valve core, accelerating the risk of air leakage. I recommend drivers develop the habit of checking valve caps whenever inflating tires. If missing, immediately replace it with a new one—it's cheap and easy to install. Don't underestimate this small part; its absence could lead to unnecessary tire replacement costs or even accidents. Regular checks extend tire lifespan and ensure safer driving.
I'm an ordinary office worker, and driving to and from work is part of my daily routine. Two years ago, I encountered a situation where the valve cap was missing. At first, I didn't pay much attention to it, but then I started feeling like the tire was always a bit soft. Later, when I went to get it inflated, the mechanic told me that the valve core was clogged with dust, causing the tire pressure to slowly drop. Not only did it waste fuel, but the car also felt unstable when turning, which was quite dangerous. That day, I was almost late and ended up spending an extra 50 yuan on inflation. Now, looking back, although the valve cap is small, without it, dirt can easily accumulate in the tire, leading to slow leaks. My advice is to pay attention to the details: occasionally check the valve stem with your hand. If the cap is missing, quickly go to an auto parts store and buy a plastic cap to replace it—it only costs a couple of yuan. Developing good habits saves you time and trouble, unlike my past self who only regretted it after something went wrong. Small oversights can turn into big problems, so always prioritize driving safety.
