How to Determine if Car Tires Are Underinflated?

[LeLydia]

There are several methods to determine if a tire is underinflated: 1. Observe whether the tire is deformed or appears flat: If the tire looks flat and the shoulder of the tire contacts the ground without any curvature, it indicates the tire is underinflated. 2. While driving, notice if the steering tends to pull to one side: If it pulls severely to one side, it suggests a significant difference in tire pressure, and the tire should be inflated promptly. 3. During driving, pay attention to the feedback from the tires: Increased noise and reduced comfort indicate slightly higher tire pressure, while the opposite suggests slightly lower pressure, meaning it’s time to inflate the tire. 4. Use a professional tire pressure gauge to check, which is the most professional and direct method.

As a car owner who frequently travels with family, I find checking tire pressure simple yet crucial. Squat down to see if the tire edges are pressing too much against the road surface—if the sides appear flattened, it indicates low pressure. If the steering wheel feels heavy or the body has slight swaying while driving, it may also signal insufficient pressure. My car has a tire pressure monitoring light that warns me immediately when there's an issue. I usually make it a habit to check monthly with a portable tire pressure gauge to ensure the values are within the recommended range on the door frame. In cold weather, pressure tends to drop, so it's especially important to check more often before winter trips. Underinflated tires not only increase fuel consumption but also accelerate wear, and prolonged neglect may lead to blowout risks. Developing a routine inspection habit ensures safety—don’t wait until problems arise on the road to regret it.

After playing with cars for a decade, I've learned that judging tire pressure relies on both experience and tools. The first choice is a tire pressure gauge – plug it into the valve stem to read the pressure; if it's below 30psi, it needs inflation. Without tools, gently kick the tire to test its firmness. Pay attention to unusual noises or bumps while driving, as these could be signs of low pressure. I recommend checking every two weeks, especially during seasons with significant temperature changes, as summer heat or winter cold can affect pressure. Proper pressure enhances handling, prevents drifting and increased fuel consumption. I often see beginners neglect this, resulting in premature tire wear. A simple check can save big money.

When I first started driving, I often forgot to check the tire pressure. Later, a friend taught me a simple method: squat down and observe if the tires appear excessively sunken. If the contact area with the ground is too large, it indicates low pressure. Kick the tires to feel their elasticity; if they're too soft, it's time to inflate them. I installed an automatic sensor in my car that alerts me immediately when the warning light comes on. Now, I make it a habit to check the pressure every time I refuel monthly—it's become second nature. Underinflated tires wear out easily and increase the risk of accidents, so laziness isn't an option. Maintaining proper pressure saves fuel and ensures safety.
