Car tire repair fluid can be used as an emergency tire repair product when the tire is punctured and loses air, and there is no immediate repair condition available. The functions of tires include: 1. Ensuring good ride comfort and smooth driving; 2. Ensuring good adhesion between the wheels and the road surface, improving the traction, braking, and off-road capability of the vehicle; 3. Transmitting driving force, braking force, and steering force through the tires to achieve vehicle control; 4. Supporting vehicle loads; 5. Reducing and absorbing vibrations and impacts during driving. Tire maintenance methods include: 1. Regularly checking tire pressure; 2. Removing debris from tire treads; 3. Inspecting tire wear and replacing tires in time according to wear conditions; 4. Performing four-wheel rotation, timely rotating tires when the vehicle shows deviation or abnormal steering to avoid excessive wear.

Tire sealant can be useful in certain situations. Based on my years of driving experience, I find it suitable for temporary emergencies. If the tire has a small puncture, such as a few millimeters in diameter, injecting sealant can quickly seal it. After reinflating, you can drive to a repair shop, saving time and effort. However, it's not a universal solution—avoid using it for large holes or sidewall damage, as it might worsen the tire's condition. The sealant residue can corrode the rubber or wheel rim over time, affecting balance and driving safety. It's good to keep a set in the car, especially for long trips, and using it with an air pump makes the process simple. Remember to clean and inspect thoroughly afterward; otherwise, professional repairs could cost more and potentially damage the vehicle.

I often use tire sealant when encountering a flat tire, and practice has shown it's convenient but requires caution. The steps are: first park in a safe location, connect the air pump to inject the liquid for quick hole sealing, and once pressure is restored, you can drive slowly to escape the predicament. It's great for emergency use in urban commuting or remote areas, helping avoid the hassle of towing. However, it can only handle small holes and isn't a permanent fix; over time, it may clog the valve stem or even affect the tire pressure sensor. From a maintenance perspective, it's advisable to keep it in an emergency kit rather than relying on it, prioritizing regular tire checks to prevent accidents. If the hole is too large, using a spare tire is more reliable—saving money doesn't necessarily mean saving trouble.

I've tried the tire repair sealant in emergencies and found it genuinely practical. For small puncture holes, it can fix the issue in minutes, allowing you to continue your journey without delay. However, don't expect it to provide a long-term seal—make sure to get proper repairs afterward. Otherwise, residue may corrode the tire interior or cause imbalance leading to vibrations. Keeping it in your car is wise, especially for novice drivers due to its simple operation, but pay attention to the instructions to avoid misuse—it's prohibited for sidewall punctures which carry higher risks. Combine this with regular tire pressure monitoring to reduce reliance, putting safety first.
