Solutions for a slow car tire leak when the cause cannot be found are: 1. Check the tread for any foreign objects: such as nails, glass, etc. If not removed, the leak will be slow. If the puncture location is relatively difficult to find, you can sprinkle water on the tire surface and observe the location of bubbles and the hissing sound of air escaping; 2. Check the aging degree of the valve stem: Some valve stems are made of rubber and may age over time, leading to a slow leak. Car tires are round, elastic rubber products mounted on various vehicles or machinery, usually installed on metal rims. They support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance.
A friend of mine has been dealing with a slow tire leak where it loses a bit of air every week, but no puncture could be found. He first tried a DIY method by mixing water and dish soap in a basin to create a soapy solution, then applied it to the tire surface, rotating the wheel inch by inch to spot where bubbles formed. It turned out there was a tiny crack near the valve stem, not a nail. He temporarily plugged it with a self-purchased tire repair strip but warned that this was only a temporary fix and not a substitute for professional repair. If you can't find the leak after trying this method, there's a high chance the issue lies inside the rim, such as rust or deformation. This is the most troublesome scenario, and the only solution is to visit a repair shop for a pressure test to pinpoint the problem. I recommend checking tire pressure weekly and keeping a portable air pump handy for emergencies. Slow leaks may seem minor, but they can lead to blowouts at high speeds, which is no small matter.
