Whether you’re a seasoned mechanic or someone who’s never peeked under a hood, chances are you’ve encountered at least one automotive myth or urban legend. These stories often stem from experienced folks like grandfathers or longtime mechanics. But does the prevalence of these tales mean they hold any truth? Well, for some, perhaps, but for others, not quite. In reality, the truth behind these myths tends to be more nuanced than simply true or false.
Myth: Nitrogen Is Better For Your Tires Than Air
There’s an old myth that nitrogen is actually better for your tires than air. And this one actually has some truth to it, though if it’s actually worth it might depend on the type of car owner you are. Using nitrogen instead of air results in far less deflation over time. It can also be better for your tire since air can contain more moisture than nitrogen. However, it’s also a lot more expensive.
Filling a tire up with nitrogen could run you upwards of $30 a pop. So, as long as you regularly check the air pressure in your tires, there isn’t a reason for most people to use nitrogen.
