Is it necessary to inflate nitrogen for family cars?

It is not necessary to inflate nitrogen for family cars because the air already contains 78% nitrogen. During the process of inflating nitrogen into tires, residual air inside the tires will mix with the nitrogen. Evacuating the tires completely could damage their internal structure, which is not advisable. Therefore, the nitrogen being inflated is mixed with air, making it essentially no different from not inflating nitrogen at all. Although inflating nitrogen is not necessary for family cars, there are still many benefits to inflating nitrogen into tires.

As a long-time user of family sedans, I've also been curious about whether filling tires with nitrogen is better. But based on my experience, it's really not worth the hassle. Regular air inflation is perfectly sufficient, costing just a few yuan, while nitrogen inflation can cost dozens or even hundreds of yuan. Unless you frequently drive in extreme conditions, such as long-distance mountain driving or racetracks, regular air is completely adequate for daily commuting in family cars. What's important is developing the habit of regularly checking tire pressure—once a month or every season—to ensure it stays within the recommended range. This helps prevent blowouts, saves fuel, and extends tire life. It's more cost-effective to save that money for better tires or routine maintenance.

As an average family car owner, I believe safety always comes first. While nitrogen inflation claims to provide more stable tire pressure and reduce risks of leaks and blowouts, in reality, for family sedans driving at moderate speeds on smooth roads, regular air inflation combined with modern tire technology is already sufficiently safe. I check tire pressure monthly, either at gas stations or with my own tools, which effectively prevents issues. There's no need to spend extra money on nitrogen inflation - those savings can be better used for other safety upgrades, like new wiper blades or brake pads. The key is regular maintenance, not chasing fancy services.

In terms of performance, nitrogen molecules are larger, resulting in less pressure change after tire inflation, which may lead to a smoother ride. However, for family cars used in urban areas, this advantage is negligible. I don't feel much difference—after three or four years of normal tire wear, regular air-filled tires perform just fine. If a tire keeps losing air, it's better to replace it rather than rely on nitrogen. I recommend choosing durable brands like Michelin or Goodyear and maintaining the correct tire pressure—that's all you need. There's no need for extra expenses and hassle.
