Is it worth inflating tires with nitrogen?

The key point is that nitrogen won't revolutionize your life, but it does have real advantages if you want to squeeze a bit more performance out of your car. The big difference is that nitrogen doesn't absorb moisture like regular air does, so your tire maintains pressure more consistently for longer and has less variation as temperature changes. That means fewer frequent tire checks, which is pretty convenient if you don't want to be checking your tires every week. Tire lifespan also tends to be slightly better because the pressure stays more consistent.

Now, whether it's actually worth it depends on your situation. If you drive very little and don't mind topping off every month or two, it's not something that'll make a huge difference. But if you drive a lot, take long trips frequently, or want to save a little on tire wear, it's worth doing. The upfront cost is kind of steep (usually more expensive than regular air), and not every shop has it, so you might end up having to find a specific place to do it. When you're getting new tires you can put nitrogen in right then, or later you can swap out your old tires and take the opportunity to do the conversion.

The thing is, it's not a miracle cure, but it's one of those things that works well in certain situations. A work vehicle that's constantly on the road? It makes sense. A car that sits in the garage most of the time? Then you can skip it without any problem.
