Do I Need to Replace the Tire if It's Punctured by a Nail?

If a tire is punctured by a nail, you can temporarily replace it with the spare tire and drive to a professional tire repair shop to have the punctured tire patched before switching it back for continued use. However, it's important to note that you should avoid driving at high speeds on highways afterward and refrain from prolonged driving. Make sure to take breaks during the journey. Here are the key functions of car tires: 1. Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. 2. Transmit traction and braking torque to ensure good adhesion between the wheels and the road surface, improving the car's power performance, braking performance, and passability. They also work with the car's suspension to cushion impacts during driving and dampen resulting vibrations. 3. Protect automotive components from severe vibrations and premature damage, adapt to the vehicle's high-speed performance, reduce driving noise, and ensure safety, handling stability, comfort, and fuel economy.
A nail in the tire doesn’t necessarily mean an immediate replacement—it depends on the puncture location and severity. If the nail is in the center of the tread, the hole is small, and there’s no cracking, driving to a repair shop for a patch (usually costing just tens of yuan) often works fine. I’ve seen many cars fixed this way and last for years. However, if the puncture is on the sidewall or the damage is severe, patching may be unsafe, and replacement is the better option. My advice: Check ASAP—avoid high speeds, pull over safely to inspect if the nail is visible, and use soapy water to test for leaks. Low pressure increases blowout risks, so make tire pressure checks a habit. Safety first—get a professional assessment, and after repair, monitor the tire regularly.
I've encountered nails puncturing tires a few times by coincidence, and feel most people tend to panic about replacing tires immediately, which really isn't necessary. I remember once driving home with a squeaking, leaking tire - turned out to be a nail right in the middle of the tread. Drove to my regular mechanic who simply patched the inner tube for 50 yuan, and it's been perfectly fine for over a year and 10,000 kilometers since. Of course, if the puncture is on the sidewall or the hole's too big with cracks spreading, replacement is wise for safety. My advice: upon discovery, first move the car to a safe parking spot avoiding prolonged driving, then search nearby repair shops on your phone to call about patching services. After repair, monitor any changes in tire noise. Adding a free pressure check during routine maintenance is convenient - don't cut corners on small expenses that could lead to big problems.
