Can a tire with a nail puncture still be used if it's not leaking air?

Generally, the tread of a tire is relatively thick. If a nail punctures the tread, you can pull it out and apply some soapy water to the puncture site to check for bubbles. If bubbles appear, it indicates that the tire is damaged and should not be used, as it can easily lead to safety accidents. Below are some related tips on car tire maintenance: 1. Regularly check tire pressure: Inflate underinflated tires promptly to maintain consistent tire pressure. Otherwise, it can cause rapid wear of low-pressure tires, increase driving resistance, raise fuel consumption, and lead to issues like directional deviation. 2. Avoid hitting obstacles: When driving at high speeds, hitting obstacles such as potholes can cause severe compression deformation between the obstacle and the tire near the rim flange. This can damage the tire's inner fabric cords, leading to air leakage from broken cords and the formation of bulges. In severe cases, it can cause the tire sidewall to rupture, resulting in sudden air loss.
I've been driving for over ten years and have encountered several instances where my tires were punctured by nails but didn't lose air. Although it might seem fine, it's actually quite risky. That time on the highway, I was driving alone when I heard an unusual noise. I got out to check and found a large nail embedded in the tire. It wasn't leaking when I pressed on it, but I didn't take it lightly—if the nail loosened at high speed, internal cracks could spread, leading to a sudden blowout, which would be dangerous. Later, I had a mechanic check it and found some rubber damage. I got it patched promptly to feel at ease. Now, I've developed a habit of keeping a portable tire pressure gauge in my car, checking the tire pressure weekly, and always inspecting the tires before long trips. I suggest you don't delay either; go to a professional shop nearby to get it checked. It's quick and cost-effective to repair, much cheaper than replacing a new tire, and safety is more important than anything. Remember, when it comes to driving, prevention is key—don't wait until something happens to regret it.
From an automotive knowledge perspective, when a tire is punctured by a nail but doesn't lose air, it's likely because the nail is lodged in the rubber layer, temporarily sealing the hole. However, don't celebrate too soon: tires have multiple internal layers, and damage may not be immediately visible even if punctured. Especially at highway speeds, rising temperatures cause air pressure fluctuations, significantly increasing the risk of the nail shifting—leading to slow leaks or even blowouts. I always advise friends in this situation to drive slowly (not exceeding 80km/h) to a repair shop for a soapy water test to check for tiny bubbles indicating leakage. Patching methods like rubber plugs or patches are simple and safe solutions; continuing to drive should only be for short emergency trips. By the way, never neglect regular tire maintenance—checking tread wear and pressure periodically extends tire life and prevents issues. Ultimately, safe driving isn't a gamble—even small risks aren't worth taking.
I've seen this all the time while working at the auto shop: tires punctured by nails but not leaking air. Customers often ask if they can still drive, and I always say stop immediately! No leak just means you're lucky—once the nail is pulled out or you hit a bumpy road, the air will leak out completely. Use soapy water or saliva to check for leaks right away. Even if there's no leak, don't drive far—just a few kilometers to the nearest repair shop. If you want to DIY, buy a tire plug kit for emergencies, but I recommend professional repair. It costs just a few dozen bucks and avoids inner tire damage. I've seen people stubbornly keep driving, only to have a blowout later that damaged the rim, costing way more to fix. Make it a habit to check your tire tread before driving, and be extra careful on gravel roads. Safety first saves big trouble.
