If a tire is punctured by a nail but is not leaking air, does it need to be replaced?

[Rodney]

Tires that have been punctured by a nail need to be replaced. Additional information: 1. Tire pressure: Strictly speaking, it refers to the air pressure inside the tire. Air pressure is the lifeblood of a tire; both too high and too low will shorten the tire's service life. 2. Seasonal factors affecting tire pressure: Tire pressure should be slightly lower in summer because high temperatures can cause the tire to heat up, and high pressure can lead to blowouts. In winter, tire pressure should be slightly higher than in summer due to thermal contraction and expansion. Generally, a car's tire pressure in winter is most suitable between 2.5 and 2.8. 3. If you frequently drive long distances on highways, the tire pressure should not be too low. It is advisable to increase it by about 0.2 compared to the standard tire pressure. If you often drive on rough roads, it is appropriate to decrease the standard tire pressure by about 0.1-0.2. Under normal circumstances, these adjustments can be negligible.
