Regular maintenance on a vehicle can sometimes feel like a daunting flurry of questions and reminders. As drivers in the Sterling, VA, area, we might ask, “Is my oil change due?” or “Are my tires healthy?” and “How long does my battery last?” And while these are typical questions with relatively simple answers, others might not seem as transparent. One of those questions is, “Should I fill my tires with nitrogen?”
There are a few reasons that one might find filling their tires with nitrogen compelling. Filling tires with nitrogen has grown in popularity over recent years, given the promise of boosted fuel economy, a reduction in air loss and rolling resistance, and improved safety. Another reason is that it helps prevent tire rot since there is a lack of moisture that would naturally occur inside tires.
So, is it all it’s cracked up to be? According to Consumer Reports, it’s more theoretically worth it than practical. The typical pitch will tell you that the nitrogen molecules are larger than the molecules in regular air, indicating that it is harder for nitrogen molecules to sneak out of the tire’s porous material. However, an independent study done by Consumer Reports showed that while nitrogen does reduce pressure loss, the reduction was only a 1.3 psi difference from regular air-filled tires over an entire year.
Considering regular air is already 78% nitrogen, when the smaller molecules in typical air leak out, it will still leave the tires with that 78% nitrogen anyway. That begs the question, is spending $5.00 or more every 2-3 months in Sterling, VA, genuinely worth it? That’s a question you’d have to ask yourself. Casey’s team will tell you that unless you drive a racecar, there is no need to fill your everyday vehicle’s tires with nitrogen. Save your money!
