How to Check for Underinflated Tires?

[Karter]

Methods to check for underinflated tires are: 1. Visually inspect all four tires to see if any are noticeably flat; 2. Use a tire pressure gauge to measure the pressure accurately; 3. Install a tire pressure monitoring system to monitor the tire pressure in real-time. The functions of tires include: 1. Supporting the entire weight of the vehicle and bearing the load; 2. Transmitting traction and braking torque to ensure adhesion between the wheels and the road; 3. Reducing and absorbing vibrations and shocks during driving to prevent severe vibrations and premature damage to vehicle components; 4. Adapting to the high-speed performance of the vehicle, reducing driving noise, and ensuring safety, handling stability, comfort, and fuel efficiency.

As a car enthusiast, I find it really important to check if the tires are underinflated, and there are several methods to do so. The most straightforward way is to use your eyes—walk around the car and observe whether any tire looks flat or uneven; if one appears noticeably sunken, it’s likely low on air. During daily driving, I also pay attention to how the car feels: if the steering suddenly becomes heavier or there’s an unusual friction noise, that’s probably a sign of low tire pressure. The most accurate method is using a tire pressure gauge, which costs just a few dollars at auto parts stores—insert it into the valve stem, read the value, and compare it to the standard pressure listed on the door frame (usually between 30-35 psi). Oh, and many new cars come with a Tire Pressure Monitoring System (TPMS), where a small light on the dashboard will alert you to low pressure. Make it a habit to check once a month, especially when the weather changes, as cold air can cause tire pressure to drop. Preventing issues in advance helps avoid blowouts, ensuring safety and better fuel efficiency.

With over 20 years of driving experience, let me share some tips! Start with a visual inspection: crouch down and check the tire sidewalls for obvious deformations or excessive contact with the ground. Then use the traditional pressure test method – a tire pressure gauge is simple to operate: unscrew the valve cap, press the gauge head on, and the reading appears instantly. If it's below the standard value, it's time to add air. You can also check while driving: after a short distance, feel the tire surface. Uneven heat distribution or one side being hotter indicates possible air leakage. Don't forget weather factors – in autumn and winter, air contracts quickly, causing tire pressure to drop more easily, so I always check more frequently during seasonal transitions. Safety first! Insufficient tire pressure not only wastes fuel but also increases the risk of skidding and accidents. Keep a portable inflator in your car for emergencies – it's handy when you need it most.

I remembered this method when I was learning to drive: using a tire pressure gauge is the most reliable way to check, and the standard pressure can usually be found on the door frame or in the manual. The steps are quite simple: park and turn off the engine, wait a few minutes for the tires to cool, unscrew the valve cap, press the gauge onto the valve stem to read the pressure, and add air if it's low. Don't forget a visual inspection: if the tire doesn't have bulges or flat spots, it's generally fine. Combine this with your driving experience—if the car feels unstable while driving, it's time to check the tire pressure early. Make it a habit to check once a month, and also inspect the valve core for leaks while you're at it.
