Can a tire still be used if the outer layer is slightly damaged?

Tires with damaged outer layers should not be continued to be used for safety reasons, and they should be replaced immediately. It is essential to have tires professionally inspected at a 4S store regularly to assess their wear and performance condition. Below are some tips for maintaining car tires: 1. Perform wheel alignment and tire rotation: For vehicles driven under normal road conditions, it is recommended to conduct wheel alignment and tire rotation every 10,000 kilometers. Misaligned wheel angles and prolonged lack of tire rotation may lead to steering deviation and abnormal tread wear. 2. Regularly check tire pressure: Tire maintenance also includes periodic pressure checks. Overinflated tires significantly reduce their lifespan, while underinflated tires can cause poor braking performance, difficulty in steering, or heavy steering, and also shorten the tire's service life. 3. Always pay attention to wear indicators: The tire wear indicators are located in the main tread grooves and appear as trapezoidal rubber protrusions. When the tread wears down to the level of these indicators, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet surfaces, the tread depth should be maintained at least 3mm. 4. Inspect tire condition: Regularly check tires for any bulges, cracks, cuts, punctures, valve stem rubber aging, and abnormal wear. Special attention should be paid to the wear on the tread and edges of the tire, which can result from poor alignment or incorrect tire pressure during driving.
The tire has a small nick on it. Having driven for ten years, I'm particularly sensitive to such minor damages. If it's just a superficial scratch on the tread that looks fine at first glance, you still need to carefully check the depth—use a ruler to measure it. If it's over 3mm deep, it's dangerous and could suddenly blow out on the highway. A crack on the sidewall is even worse—never use it, as a blowout could cause the car to lose control. I once ignored a small nick and didn't replace the tire, only to have it suddenly lose air the next day on the highway, nearly causing an accident. Luckily, I managed to pull over in time. Since then, I've learned my lesson: take photos of any damage and go straight to a repair shop for assessment. Saving a little money isn't worth risking your life. Tires are a car's critical protection—don't gamble with safety over small savings. Early checks can prevent costly repairs later.
