Do I Need to Replace the Tire if It's Punctured by a Nail but Not Losing Air?

If a tire is punctured by a nail but not losing air, there is no need to replace it. You can drive the car at a low speed to a repair shop to have the tire patched. Here are some precautions regarding tire maintenance: 1. Pay attention to tire pressure. Both overinflation and underinflation can shorten the lifespan of a tire. Underinflation increases tire deformation, leading to cracks on the tire sidewalls and causing flexing movements, which generate excessive heat, accelerating rubber aging, fatigue of the cord layers, and cord breakage. Underinflation also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. Overinflation causes excessive stretching of the tire cords, reducing the tire's elasticity and increasing the load on the car while driving. If impacted, it may lead to internal cracks or blowouts. Overinflation also accelerates tread wear and reduces puncture resistance. 2. Regularly check the front wheel alignment. Front wheel alignment significantly affects tire lifespan, with toe-in and camber being the primary factors. Excessive camber mainly accelerates wear on the tire shoulders, while incorrect toe-in (too little or too much) primarily accelerates wear on the inner or outer sides of the tire. 3. Be mindful of your driving habits. While driving, apart from handling road conditions, drivers should choose their path carefully to avoid sharp objects like stones, glass, and metal that could puncture or scratch the tires, as well as chemical spills that could adhere to and corrode the tires. When driving on roads with significant curvature, try to stay in the center to reduce uneven tire wear caused by increased load on one side.
I've been driving for many years, and if a tire gets punctured by a nail without losing air, don't take it lightly and assume it's fine. The nail might be deeply embedded, damaging the internal fiber structure of the tire, which could lead to a potential blowout risk—especially dangerous when driving on highways. My advice is not to pull out the nail yourself; instead, drive immediately to a professional tire shop for inspection. They will use tools to assess the damage. If the puncture is in the center of the tread, it can often be safely repaired for just a few dozen bucks, which is a great deal. However, if the puncture is on the sidewall or near the edge, you must replace the tire, as a repair won’t hold up. Tires are the foundation of driving safety, and it’s not worth risking your safety to save a little money. I know someone who ignored it and ended up with a blowout on the road, nearly causing an accident. Remember, regularly checking tire pressure and surface conditions can help detect issues early and avoid trouble.
