Do I have to replace the tire if it gets punctured by a nail?

Generally, you don't need to replace the tire if it gets punctured by a nail. It can be repaired directly without major issues. Normally, a tire can be patched 3-5 times without problems, but it shouldn't be punctured in the same spot repeatedly, as this could create a large area of damage and pose a risk. If the tire tread is worn flat or the damage is severe, a new tire should be replaced. Below is an introduction to the functions of tires: Tires are one of the most important components of a car. Their main functions include: supporting the entire weight of the vehicle and bearing the load of the car; transmitting traction and braking torque to ensure the adhesion between the wheels and the road; reducing and absorbing vibrations and impacts during driving to prevent severe vibrations and early damage to car components; adapting to the high-speed performance of the vehicle and reducing driving noise; ensuring driving safety, handling stability, comfort, and fuel efficiency.
I've seen tires getting punctured by nails quite a few times over my years of driving, and it's definitely not always necessary to replace the tire immediately. The key is where the nail is located: if it's in the tread pattern right in the middle of the tire, it can usually be repaired. The mechanic will remove the nail and patch it from the inside using a mushroom plug or a rubber strip, which only costs a few dozen yuan. However, if the nail is on the sidewall or near the edge, it can't be repaired—you'll need to replace the tire directly, as those areas are too thin and prone to leaks or blowouts after repair. I recommend not pulling the nail out yourself; instead, drive to a reliable repair shop and let them check the location, depth, and the tire's aging condition. After patching, the tire should be fine to drive on, but remember to check the air pressure regularly to prevent accidents. Replacing a tire is more expensive, but safety always comes first.
