This is because the tires currently in use are all tubeless tires, with a normal tire pressure of 2.2-2.6 bar. It is normal for the tires to appear slightly flat as long as they reach the standard pressure specified in the vehicle's manual during inflation, regardless of whether they look flat or not. However, car owners must pay attention to ensuring that the tire pressure is just right—not too high or too low—otherwise, it will accelerate tire wear. Refer to the manufacturer's recommended tire pressure values found in the vehicle's user manual, near the B-pillar, or on the fuel tank cap. If you frequently drive on highways, you can increase the tire pressure by 5%~10% above the reference value to avoid tire standing waves. Not only can sharp objects cause a tire blowout, but insufficient tire pressure can also easily lead to high-speed blowouts due to the standing wave phenomenon. Tire standing waves will cause intense friction among rubber molecules inside the tire, leading to a rapid rise in temperature, separation of rubber layers, accelerated damage to the tire body, and continuous twisting of the internal steel wires or high-strength nylon cords by the "waves," resulting in material fatigue and fracture, ultimately causing a blowout. If car owners do not have the habit of regularly checking tire pressure (for vehicles without a tire pressure monitoring system) and only occasionally around the car for a quick visual inspection, problems can easily arise. When tire pressure drops from 2.3 bar to 1.9 bar, there may not be much visible change, but 1.9 bar is already considered underinflated. Only when the pressure drops to 1.5 bar or 1.1 bar will the tires appear noticeably flat, and kicking the wheels will give a distinct "soft" feeling. Therefore, visual inspection can only detect severely low tire pressure situations. Whether the tire pressure meets the standard cannot be accurately determined by the naked eye. The best approach is to promptly visit a repair shop and seek professional assistance from a technician if any issues are detected.

Recently I encountered the same issue - the tires looked deflated but the pressure readings were normal. At first I thought the pressure gauge was broken, so I quickly rechecked with my home digital tire pressure gauge to confirm everything was fine. Later when discussing with friends, I learned that some tires are designed this way. For example, SUV rear tires have thicker sidewalls which can appear visually flat, but this doesn't affect driving. However, frequently parking on uneven surfaces or uneven loading might worsen the situation. My suggestion is don't panic yet. Try this simple test: use your flashlight to check for sidewall cracks or bulges, or gently tap the tire to listen for uniform sound. Make it a habit to check pressure weekly maintaining recommended levels. If still concerned, visit a nearby repair shop for a free tire system scan to rule out safety hazards. Safety comes first - don't let this minor issue affect your driving experience.

As a seasoned driver with over a decade of experience, I've encountered many similar situations: tires appearing deflated but showing normal pressure readings. Most cases are optical illusions caused by tire design or uneven parking—just ensure cold tire pressure checks with a home gauge are accurate, and you're fine. But beware: inaccurate gauges are common, so consider upgrading to a professional-grade one for verification. Also, loading matters—heavier trunk weight naturally flattens rear tires slightly. During weekly , I casually check wheel alignment balance; an easier solution is having car wash shops perform quick tire health checks to prevent issues. Small tire problems can escalate annoyingly, so address them early to avoid blowout risks.

When encountering low tire pressure, as a DIY car enthusiast, I first check if the tire pressure gauge is properly calibrated—digital ones are more reliable than old-fashioned analog ones. Then, I visually inspect the tires for any deformations or bulges; aging tire sidewalls are prone to issues and may need replacement. It's advisable to regularly check the pressure instead of waiting for a warning. An additional tip: around the car before driving to check for any visible cracks. Simple maintenance can save on repair costs.

As an urban office worker, my car is often parked on the roadside, and the tires appear flat but the app shows normal pressure. It might be due to design or temperature changes causing visual discrepancies. Use a pressure gauge to measure multiple times to rule out false alarms. New cars with sensor alarms are much more accurate; it's advisable to drive to a 4S shop for a comprehensive tire pressure system scan. Don't overlook safety: maintain recommended pressure values daily to reduce accidents.

I'm always alert about tire pressure appearing low: it could be due to inaccurate pressure gauges or internal tire wear/deformation. I make it a habit to check pressure in cold tire conditions; if any doubt arises, I immediately stop to inspect for external damage/deformation. Monthly checks are recommended to prevent early-stage hazards; for urgent issues, head to a professional shop for comprehensive scanning to eliminate safety risks. Never underestimate minor issues that could lead to major accidents.
