Do I Need to Repair a Tire if It Has a Nail but Isn't Leaking Air?

Whether a tire needs to be repaired after being punctured by a nail depends on the following two scenarios: 1. If the puncture is on the tread and the tire can still be driven, then repair is not necessary. 2. If the puncture is on the sidewall, the spare tire should be replaced as soon as possible due to the risk of a blowout. The methods for dealing with foreign objects puncturing a tire are as follows: 1. If a tire is punctured by a nail but isn't leaking air, it means the nail hasn't penetrated completely. In this case, the spare tire should be replaced as soon as possible, and the punctured tire should be inspected at a repair location. If there is absolutely no air leakage, then repair may not be necessary. 2. If there is no spare tire, be careful not to remove the nail, as doing so could create a safety hazard while driving.
I've seen many cases where tires were punctured by nails but didn't leak. As someone who drives frequently, I always feel it's too risky not to repair them. Even if there's no leakage now, the nail may have already damaged the internal structure. Under high temperature and pressure while driving, the tire could suddenly leak or blow out at any moment. Once, my neighbor was careless like this, and within a few days, their tire blew out on the highway—fortunately, no one was hurt. Repairing a tire is simple and quick, and it doesn't cost much, just a few dozen bucks. Take it to a professional shop to check for internal and external damage, and patch it if necessary. Don't skimp on this small expense—safety comes first, and it can also extend the tire's lifespan. I recommend developing a habit of checking your tires monthly, especially for foreign objects on the tread. Early detection leads to early repair.
A nail in the tire without air leakage doesn't mean it can be ignored. From what I understand, the nail may get stuck in the sidewall or inner liner, causing a slow leak, or increase risks due to friction while driving. Repair is essential. Professional repair shops will remove the nail to test for leaks; if there's damage, they'll perform a hot or cold patch to prevent further issues. The cost is usually between 50 to 100 yuan, much more economical compared to the thousand or so yuan for a new tire. A friend of mine once overlooked this and ended up with a ruined tire, wasting more money. Regular checks on tire pressure and appearance are also important to avoid accumulating hidden dangers. Driving is a daily activity, and details matter for safety. Fixing it early brings peace of mind.
