Do car tires need inflation?

[McCourtney]

It is necessary to inflate car tires based on their condition: if the tire has damage; or if the tire pressure is too low. Daily maintenance for car tires can include the following: Check the tires: Inspect all tires, including the spare, at least once a month for pressure when they are cold. Avoid speeding: Do not exceed reasonable speeds required by driving conditions and legal limits (e.g., slow down or avoid obstacles like rocks or potholes ahead). Regular inspections: Perform wheel alignment and balancing periodically to ensure driving safety and achieve optimal mileage.

When I first bought my car, I didn't know much about it. Later, I realized that tires indeed need regular inflation. During normal driving, tires slowly lose air, especially when the weather changes significantly, the air pressure fluctuations become more noticeable. I check them myself every month using a tire pressure gauge. Generally, for family cars, maintaining a pressure between 2.3 and 2.5 bar is ideal. If the pressure is too low, you'll feel the steering wheel become heavier, and the tire sidewalls may develop wave-like deformations, which could lead to complete failure over time. Once, during a trip, I noticed the car pulling to one side, and after inflating the tires properly, the fuel efficiency improved significantly. Remember not to overinflate them, as excessive tire pressure can cause blowouts when hitting potholes. I recommend keeping a portable air pump in your car. You can either use the free air pumps at gas stations or spend a few dozen bucks on an electric pump.

As a veteran driver with twenty years of experience, let me tell you, tire pressure is not something to be taken lightly. Last week, a car in our neighborhood was driving with a flat tire, and the sidewall was worn down to the steel wires. In fact, tires are like balloons—they naturally lose air even without a puncture. For every 10-degree drop in temperature, tire pressure decreases by about 0.1. I usually check the manufacturer's recommended values on the fuel cap or driver's door frame and measure it with a mechanical gauge when the tires are cold. Nowadays, many new cars come with tire pressure monitoring systems, and when that little yellow light comes on, you should pay attention. The most dangerous consequence of low tire pressure is a blowout at high speeds, and it also increases braking distance by several meters. I always keep an air pump in my trunk and check all four tires before any long trip. If you notice one side consistently losing air, chances are there's a nail in it.

Of course, tires need to be inflated! Look at my neighbor's car tires—they've worn into a square shape, yet he still hesitates to top them up. In fact, underinflated tires increase the contact area, which can raise fuel consumption by over 5%. Driving like this for half a year could cost you more in fuel than buying new tires. I recommend getting a digital inflator for just a few dozen bucks—it takes only five minutes to do it yourself at home. Adjustments are necessary across seasons: increase tire pressure by 0.2 in winter and decrease it by 0.1 in summer. If you frequently carry heavy loads, you can set the rear tire pressure slightly higher. But never follow those who pump it up to 3.5—that’s just asking for a blowout. By the way, when you go for maintenance at the 4S shop, ask them to check the pressure for free—their equipment is more accurate.

During a weekend road trip, I noticed the steering wheel shaking. After pulling over, I found the left front tire pressure had dropped to just 1.8 bar. Maintaining proper tire pressure is especially crucial for long-distance driving. I once witnessed a tire blowout scene at a highway rest area with rubber debris scattered everywhere. Now I've developed a habit: before departure, I use a pen-type tire gauge to measure all four tires and inflate them to standard values; when stopping at rest areas every 300 km, I manually check tire temperature. If tire pressure is 0.5 bar below standard, tire lifespan decreases by about 15%. Mountain roads are more dangerous - underinflated tires heat up rapidly during continuous downhill braking. A reminder for novice drivers: repaired tires tend to lose air faster and are recommended to be placed on rear wheels. Owners of wide-body modified vehicles should pay particular attention to proper tire pressure matching.

When it comes to tire maintenance, I'm the most qualified to speak—I spent three years working in a repair shop when I was younger. Underinflated tires don't just waste fuel; they also damage the suspension system. A tire low on air is like a deflated ball—when you go over a speed bump, the rim directly impacts the road, and the shock absorbers won't last more than three years before failing. Here's a professional inspection method: measure the baseline when the car is cold, then drive ten kilometers and measure again. If the pressure difference exceeds 0.3, there might be a slow leak. If you notice abnormal tire pressure loss, check the valve stem—rubber aging and cracking are common causes. Brand-name tires can last five years, but incorrect tire pressure will wear them out in three. Remember to tighten the valve cap after inflating, or dirt getting inside will cause even more trouble.
