Why is there a nail in the tire but no air leakage?

The reasons why there is a nail in the tire but no air leakage are: 1. The nail did not penetrate through; 2. The nail penetrated the front side of the tire, and since it's a tubeless tire, no air leaks or leaks slowly if the nail is not pulled out; 3. The nail penetrated the sidewall of the tire. The solution is to simply pull it out with pliers as long as there is no air leakage. Car tires are one of the important components of a vehicle, directly in contact with the road surface, working together with the car's suspension to cushion the impact during driving, ensuring good ride comfort and smooth driving. The function of the tire is to ensure good adhesion between the wheel and the road surface, improving the car's traction, braking, and off-road capability.
Once I saw a nail stuck in my tire and panicked a bit, but then realized it hadn't caused a complete air leak, which gave me some relief. This might be because the nail was lodged in the rubber surface of the tire without penetrating the inner reinforced layer, essentially just leaving a small mark without damaging the airtight layer. Nowadays, many tires come with puncture-resistant designs or self-sealing layers that automatically plug small holes when encountering nails, preventing immediate air leaks. However, this is no reason to be complacent. The fact that the nail is still stuck there means the risk hasn't been eliminated. Vibrations while driving or increased pressure during turns could fully puncture the tire, leading to a blowout. I recommend driving to a nearby tire shop immediately for a check-up. A technician can remove the nail and test for slow leaks. If the hole isn't too big, a simple patch might suffice—don't wait until you're stranded in the middle of the night. Safety should always come first, and making a habit of regularly checking tire pressure can help prevent problems before they arise.
I always keep a tire pressure monitor in my car and learned to analyze such situations after experiencing them. If a tire is punctured by a nail but isn't losing air, it's likely because the nail is in a thick part of the tread, like the outer tread pattern where the rubber layer is tough, and the nail hasn't pierced the internal fabric structure, sealing the air. Some tires have rubber fillers that can temporarily seal small holes, but don't assume it's fine—the sharp edges of the nail can wear the inner liner, and over time, pressure buildup may cause sudden air loss, especially at high speeds, doubling the risk. I once tried pulling out a nail myself to check for leaks but messed up, ending up needing a tow for repairs. For safe handling, park the car without moving the tire, call roadside assistance, or drive slowly to a professional shop where they can safely remove the nail with tools and ensure the rim isn't damaged. Remember, don't take tires lightly—regular maintenance can save you from unnecessary expenses.
After decades of driving, tire issues are what I fear most. I've encountered situations where nails punctured the tire without causing immediate deflation a few times. The reason might be that the nail was too short or entered at an angle, not piercing through to the inner chamber, thus maintaining the air pressure. However, in this state, the tire's strength is compromised, and foreign objects can enlarge the crack during driving, leading to a risk of blowout, especially on bumpy roads or during sharp turns. I strongly advise against procrastination—slow down immediately, pull over, turn off the engine, check for obvious deformations in the tire tread, and then call for a tow truck to get it repaired. Removing the nail is best left to professionals. Simply put, safety comes first. Spending a little money to replace the tire or patch the hole promptly can save you from the bigger hassle of breaking down midway. Develop the habit of checking tire pressure monthly to nip potential problems in the bud.
